first-hand data at the time
of the research project
Low
One of the most obvious advantages is that, compared to primary research, secondary research is inexpensive . Primary research usually requires spending a lot of money. For instance, members of the research team should be paid salaries. There are often travel and transportation costs. You may need to pay for office space and equipment, and compensate your participants for taking part. There may be other overhead costs too.
These costs do not exist when doing secondary research. Although researchers may need to purchase secondary data sets, this is always less costly than if the research were to be conducted from scratch.
As an undergraduate or graduate student, your dissertation project won't need to be an expensive endeavour. Thus, it is useful to know that you can further reduce costs, by using freely available secondary data sets.
But this is far from the only consideration.
Most students value another important advantage of secondary research, which is that secondary research saves you time . Primary research usually requires months spent recruiting participants, providing them with questionnaires, interviews, or other measures, cleaning the data set, and analysing the results. With secondary research, you can skip most of these daunting tasks; instead, you merely need to select, prepare, and analyse an existing data set.
Moreover, you probably won’t need a lot of time to obtain your secondary data set, because secondary data is usually easily accessible . In the past, students needed to go to libraries and spend hours trying to find a suitable data set. New technologies make this process much less time-consuming. In most cases, you can find your secondary data through online search engines or by contacting previous researchers via email.
A third important advantage of secondary research is that you can base your project on a large scope of data . If you wanted to obtain a large data set yourself, you would need to dedicate an immense amount of effort. What's more, if you were doing primary research, you would never be able to use longitudinal data in your graduate or undergraduate project, since it would take you years to complete. This is because longitudinal data involves assessing and re-assessing a group of participants over long periods of time.
When using secondary data, however, you have an opportunity to work with immensely large data sets that somebody else has already collected. Thus, you can also deal with longitudinal data, which may allow you to explore trends and changes of phenomena over time.
With secondary research, you are relying not only on a large scope of data, but also on professionally collected data . This is yet another advantage of secondary research. For instance, data that you will use for your secondary research project has been collected by researchers who are likely to have had years of experience in recruiting representative participant samples, designing studies, and using specific measurement tools.
If you had collected this data yourself, your own data set would probably have more flaws, simply because of your lower level of expertise when compared to these professional researchers.
The first such disadvantage is that your secondary data may be, to a greater or lesser extent, inappropriate for your own research purposes. This is simply because you have not collected the data yourself.
When you collect your data personally, you do so with a specific research question in mind. This makes it easy to obtain the relevant information. However, secondary data was always collected for the purposes of fulfilling other researchers’ goals and objectives.
Thus, although secondary data may provide you with a large scope of professionally collected data, this data is unlikely to be fully appropriate to your own research question. There are several reasons for this. For instance, you may be interested in the data of a particular population, in a specific geographic region, and collected during a specific time frame. However, your secondary data may have focused on a slightly different population, may have been collected in a different geographical region, or may have been collected a long time ago.
Apart from being potentially inappropriate for your own research purposes, secondary data could have a different format than you require. For instance, you might have preferred participants’ age to be in the form of a continuous variable (i.e., you want your participants to have indicated their specific age). But the secondary data set may contain a categorical age variable; for example, participants might have indicated an age group they belong to (e.g., 20-29, 30-39, 40-49, etc.). Or another example: A secondary data set may contain too few ethnic categories (e.g., “White” and “Other”), while you would ideally want a wider range of racial categories (e.g., “White”, “Black or African American”, “American Indian”, and “Asian”). Differences such as these mean that secondary data may not be perfectly appropriate for your research.
The above two disadvantages may lead to yet another one: the existing data set may not answer your own research question(s) in an ideal way. As noted above, secondary data was collected with a different research question in mind, and this may limit its application to your own research purpose.
Unfortunately, the list of disadvantages does not end here. An additional weakness of secondary data is that you have a lack of control over the quality of data. All researchers need to establish that their data is reliable and valid. But if the original researchers did not establish the reliability and validity of their data, this may limit its reliability and validity for your research as well. To establish reliability and validity, you are usually advised to critically evaluate how the data was gathered, analysed, and presented.
But here lies the final disadvantage of doing secondary research: original researchers may fail to provide sufficient information on how their research was conducted. You might be faced with a lack of information on recruitment procedures, sample representativeness, data collection methods, employed measurement tools and statistical analyses, and the like. This may require you to take extra steps to obtain such information, if that is possible at all.
TABLE 2 provides a full summary of advantages and disadvantages of secondary research:
ADVANTAGES | DISADVANTAGES |
---|---|
Inexpensive: Conducting secondary research is much cheaper than doing primary research | Inappropriateness: Secondary data may not be fully appropriate for your research purposes |
Saves time: Secondary research takes much less time than primary research | Wrong format: Secondary data may have a different format than you require |
Accessibility: Secondary data is usually easily accessible from online sources. | May not answer your research question: Secondary data was collected with a different research question in mind |
Large scope of data: You can rely on immensely large data sets that somebody else has collected | Lack of control over the quality of data: Secondary data may lack reliability and validity, which is beyond your control |
Professionally collected data: Secondary data has been collected by researchers with years of experience | Lack of sufficient information: Original authors may not have provided sufficient information on various research aspects |
At this point, we should ask: “What are the methods of secondary research?” and “When do we use each of these methods?” Here, we can differentiate between three methods of secondary research: using a secondary data set in isolation , combining two secondary data sets, and combining secondary and primary data sets. Let’s outline each of these separately, and also explain when to use each of these methods.
Initially, you can use a secondary data set in isolation – that is, without combining it with other data sets. You dig and find a data set that is useful for your research purposes and then base your entire research on that set of data. You do this when you want to re-assess a data set with a different research question in mind.
Let’s illustrate this with a simple example. Suppose that, in your research, you want to investigate whether pregnant women of different nationalities experience different levels of anxiety during different pregnancy stages. Based on the literature, you have formed an idea that nationality may matter in this relationship between pregnancy and anxiety.
If you wanted to test this relationship by collecting the data yourself, you would need to recruit many pregnant women of different nationalities and assess their anxiety levels throughout their pregnancy. It would take you at least a year to complete this research project.
Instead of undertaking this long endeavour, you thus decide to find a secondary data set – one that investigated (for instance) a range of difficulties experienced by pregnant women in a nationwide sample. The original research question that guided this research could have been: “to what extent do pregnant women experience a range of mental health difficulties, including stress, anxiety, mood disorders, and paranoid thoughts?” The original researchers might have outlined women’s nationality, but weren’t particularly interested in investigating the link between women’s nationality and anxiety at different pregnancy stages. You are, therefore, re-assessing their data set with your own research question in mind.
Your research may, however, require you to combine two secondary data sets . You will use this kind of methodology when you want to investigate the relationship between certain variables in two data sets or when you want to compare findings from two past studies.
To take an example: One of your secondary data sets may focus on a target population’s tendency to smoke cigarettes, while the other data set focuses on the same population’s tendency to drink alcohol. In your own research, you may thus be looking at whether there is a correlation between smoking and drinking among this population.
Here is a second example: Your two secondary data sets may focus on the same outcome variable, such as the degree to which people go to Greece for a summer vacation. However, one data set could have been collected in Britain and the other in Germany. By comparing these two data sets, you can investigate which nation tends to visit Greece more.
Finally, your research project may involve combining primary and secondary data . You may decide to do this when you want to obtain existing information that would inform your primary research.
Let’s use another simple example and say that your research project focuses on American versus British people’s attitudes towards racial discrimination. Let’s say that you were able to find a recent study that investigated Americans’ attitudes of these kind, which were assessed with a certain set of measures. However, your search finds no recent studies on Britons’ attitudes. Let’s also say that you live in London and that it would be difficult for you to assess Americans’ attitudes on the topic, but clearly much more straightforward to conduct primary research on British attitudes.
In this case, you can simply reuse the data from the American study and adopt exactly the same measures with your British participants. Your secondary data is being combined with your primary data. Alternatively, you may combine these types of data when the role of your secondary data is to outline descriptive information that supports your research. For instance, if your project is focusing on attitudes towards McDonald’s food, you may want to support your primary research with secondary data that outlines how many people eat McDonald’s in your country of choice.
TABLE 3 summarises particular methods and purposes of secondary research:
METHOD | PURPOSE |
---|---|
Using secondary data set in isolation | Re-assessing a data set with a different research question in mind |
Combining two secondary data sets | Investigating the relationship between variables in two data sets or comparing findings from two past studies |
Combining secondary and primary data sets | Obtaining existing information that informs your primary research |
We have already provided above several examples of using quantitative secondary data. This type of data is used when the original study has investigated a population’s tendency to smoke or drink alcohol, the degree to which people from different nationalities go to Greece for their summer vacation, or the degree to which pregnant women experience anxiety.
In all these examples, outcome variables were assessed by questionnaires, and thus the obtained data was numerical.
Quantitative secondary research is much more common than qualitative secondary research. However, this is not to say that you cannot use qualitative secondary data in your research project. This type of secondary data is used when you want the previously-collected information to inform your current research. More specifically, it is used when you want to test the information obtained through qualitative research by implementing a quantitative methodology.
For instance, a past qualitative study might have focused on the reasons why people choose to live on boats. This study might have interviewed some 30 participants and noted the four most important reasons people live on boats: (1) they can lead a transient lifestyle, (2) they have an increased sense of freedom, (3) they feel that they are “world citizens”, and (4) they can more easily visit their family members who live in different locations. In your own research, you can therefore reuse this qualitative data to form a questionnaire, which you then give to a larger population of people who live on boats. This will help you to generalise the previously-obtained qualitative results to a broader population.
Importantly, you can also re-assess a qualitative data set in your research, rather than using it as a basis for your quantitative research. Let’s say that your research focuses on the kind of language that people who live on boats use when describing their transient lifestyles. The original research did not focus on this research question per se – however, you can reuse the information from interviews to “extract” the types of descriptions of a transient lifestyle that were given by participants.
TABLE 4 highlights the two main types of secondary data and their associated purposes:
TYPES | PURPOSES |
---|---|
Quantitative | Both can be used when you want to (a) inform your current research with past data, and (b) re-assess a past data set |
Qualitative | Both can be used when you want to (a) inform your current research with past data, and (b) re-assess a past data set |
Internal sources of data are those that are internal to the organisation in question. For instance, if you are doing a research project for an organisation (or research institution) where you are an intern, and you want to reuse some of their past data, you would be using internal data sources.
The benefit of using these sources is that they are easily accessible and there is no associated financial cost of obtaining them.
External sources of data, on the other hand, are those that are external to an organisation or a research institution. This type of data has been collected by “somebody else”, in the literal sense of the term. The benefit of external sources of data is that they provide comprehensive data – however, you may sometimes need more effort (or money) to obtain it.
Let’s now focus on different types of internal and external secondary data sources.
There are several types of internal sources. For instance, if your research focuses on an organisation’s profitability, you might use their sales data . Each organisation keeps a track of its sales records, and thus your data may provide information on sales by geographical area, types of customer, product prices, types of product packaging, time of the year, and the like.
Alternatively, you may use an organisation’s financial data . The purpose of using this data could be to conduct a cost-benefit analysis and understand the economic opportunities or outcomes of hiring more people, buying more vehicles, investing in new products, and so on.
Another type of internal data is transport data . Here, you may focus on outlining the safest and most effective transportation routes or vehicles used by an organisation.
Alternatively, you may rely on marketing data , where your goal would be to assess the benefits and outcomes of different marketing operations and strategies.
Some other ideas would be to use customer data to ascertain the ideal type of customer, or to use safety data to explore the degree to which employees comply with an organisation’s safety regulations.
The list of the types of internal sources of secondary data can be extensive; the most important thing to remember is that this data comes from a particular organisation itself, in which you do your research in an internal manner.
The list of external secondary data sources can be just as extensive. One example is the data obtained through government sources . These can include social surveys, health data, agricultural statistics, energy expenditure statistics, population censuses, import/export data, production statistics, and the like. Government agencies tend to conduct a lot of research, therefore covering almost any kind of topic you can think of.
Another external source of secondary data are national and international institutions , including banks, trade unions, universities, health organisations, etc. As with government, such institutions dedicate a lot of effort to conducting up-to-date research, so you simply need to find an organisation that has collected the data on your own topic of interest.
Alternatively, you may obtain your secondary data from trade, business, and professional associations . These usually have data sets on business-related topics and are likely to be willing to provide you with secondary data if they understand the importance of your research. If your research is built on past academic studies, you may also rely on scientific journals as an external data source.
Once you have specified what kind of secondary data you need, you can contact the authors of the original study.
As a final example of a secondary data source, you can rely on data from commercial research organisations. These usually focus their research on media statistics and consumer information, which may be relevant if, for example, your research is within media studies or you are investigating consumer behaviour.
TABLE 5 summarises the two sources of secondary data and associated examples:
INTERNAL SOURCES | EXTERNAL SOURCES |
---|---|
Definition: Internal to the organisation or research institution where you conduct your research | Definition: External to the organisation or research institution where you conduct your research |
Examples: • Sales data • Financial data • Transport data • Marketing data • Customer data • Safety data | Examples: |
At this point, you should have a clearer understanding of secondary research in general terms.
Now it may be useful to focus on the actual process of doing secondary research. This next section is organised to introduce you to each step of this process, so that you can rely on this guide while planning your study. At the end of this blog post, in Table 6 , you will find a summary of all the steps of doing secondary research.
For an undergraduate thesis, you are often provided with a specific research question by your supervisor. But for most other types of research, and especially if you are doing your graduate thesis, you need to arrive at a research question yourself.
The first step here is to specify the general research area in which your research will fall. For example, you may be interested in the topic of anxiety during pregnancy, or tourism in Greece, or transient lifestyles. Since we have used these examples previously, it may be useful to rely on them again to illustrate our discussion.
Once you have identified your general topic, your next step consists of reading through existing papers to see whether there is a gap in the literature that your research can fill. At this point, you may discover that previous research has not investigated national differences in the experiences of anxiety during pregnancy, or national differences in a tendency to go to Greece for a summer vacation, or that there is no literature generalising the findings on people’s choice to live on boats.
Having found your topic of interest and identified a gap in the literature, you need to specify your research question. In our three examples, research questions would be specified in the following manner: (1) “Do women of different nationalities experience different levels of anxiety during different stages of pregnancy?”, (2) “Are there any differences in an interest in Greek tourism between Germans and Britons?”, and (3) “Why do people choose to live on boats?”.
It is at this point, after reviewing the literature and specifying your research questions, that you may decide to rely on secondary data. You will do this if you discover that there is past data that would be perfectly reusable in your own research, therefore helping you to answer your research question more thoroughly (and easily).
But how do you discover if there is past data that could be useful for your research? You do this through reviewing the literature on your topic of interest. During this process, you will identify other researchers, organisations, agencies, or research centres that have explored your research topic.
Somewhere there, you may discover a useful secondary data set. You then need to contact the original authors and ask for a permission to use their data. (Note, however, that this happens only if you are relying on external sources of secondary data. If you are doing your research internally (i.e., within a particular organisation), you don’t need to search through the literature for a secondary data set – you can just reuse some past data that was collected within the organisation itself.)
In any case, you need to ensure that a secondary data set is a good fit for your own research question. Once you have established that it is, you need to specify the reasons why you have decided to rely on secondary data.
For instance, your choice to rely on secondary data in the above examples might be as follows: (1) A recent study has focused on a range of mental difficulties experienced by women in a multinational sample and this data can be reused; (2) There is existing data on Germans’ and Britons’ interest in Greek tourism and these data sets can be compared; and (3) There is existing qualitative research on the reasons for choosing to live on boats, and this data can be relied upon to conduct a further quantitative investigation.
Because such disadvantages of secondary data can limit the effectiveness of your research, it is crucial that you evaluate a secondary data set. To ease this process, we outline here a reflective approach that will allow you to evaluate secondary data in a stepwise fashion.
During this step, you also need to pay close attention to any differences in research purposes and research questions between the original study and your own investigation. As we have discussed previously, you will often discover that the original study had a different research question in mind, and it is important for you to specify this difference.
Let’s put this step of identifying the aim of the original study in practice, by referring to our three research examples. The aim of the first research example was to investigate mental difficulties (e.g., stress, anxiety, mood disorders, and paranoid thoughts) in a multinational sample of pregnant women.
How does this aim differ from your research aim? Well, you are seeking to reuse this data set to investigate national differences in anxiety experienced by women during different pregnancy stages. When it comes to the second research example, you are basing your research on two secondary data sets – one that aimed to investigate Germans’ interest in Greek tourism and the other that aimed to investigate Britons’ interest in Greek tourism.
While these two studies focused on particular national populations, the aim of your research is to compare Germans’ and Britons’ tendency to visit Greece for summer vacation. Finally, in our third example, the original research was a qualitative investigation into the reasons for living on boats. Your research question is different, because, although you are seeking to do the same investigation, you wish to do so by using a quantitative methodology.
Importantly, in all three examples, you conclude that secondary data may in fact answer your research question. If you conclude otherwise, it may be wise to find a different secondary data set or to opt for primary research.
Let’s say that, in our example of research on pregnancy, data was collected by the UK government; that in our example of research on Greek tourism, the data was collected by a travel agency; and that in our example of research on the reasons for choosing to live on boats, the data was collected by researchers from a UK university.
Let’s also say that you have checked the background of these organisations and researchers, and that you have concluded that they all have a sufficiently professional background, except for the travel agency. Given that this agency’s research did not lead to a publication (for instance), and given that not much can be found about the authors of the research, you conclude that the professionalism of this data source remains unclear.
Original authors should have documented all their sample characteristics, measures, procedures, and protocols. This information can be obtained either in their final research report or through contacting the authors directly.
It is important for you to know what type of data was collected, which measures were used, and whether such measures were reliable and valid (if they were quantitative measures). You also need to make a clear outline of the type of data collected – and especially the data relevant for your research.
Let’s say that, in our first example, researchers have (among other assessed variables) used a demographic measure to note women’s nationalities and have used the State Anxiety Inventory to assess women’s anxiety levels during different pregnancy stages, both of which you conclude are valid and reliable tools. In our second example, the authors might have crafted their own measure to assess interest in Greek tourism, but there may be no established validity and reliability for this measure. And in our third example, the authors have employed semi-structured interviews, which cover the most important reasons for wanting to live on boats.
Ideally, you want your secondary data to have been collected within the last five years. For the sake of our examples, let’s say that all three original studies were conducted within this time-range.
We have already noted that you need to evaluate the reliability and validity of employed measures. In addition to this, you need to evaluate how the sample was obtained, whether the sample was large enough, if the sample was representative of the population, if there were any missing responses on employed measures, whether confounders were controlled for, and whether the employed statistical analyses were appropriate. Any drawbacks in the original methodology may limit your own research as well.
For the sake of our examples, let’s say that the study on mental difficulties in pregnant women recruited a representative sample of pregnant women (i.e., they had different nationalities, different economic backgrounds, different education levels, etc.) in maternity wards of seven hospitals; that the sample was large enough (N = 945); that the number of missing values was low; that many confounders were controlled for (e.g., education level, age, presence of partnership, etc.); and that statistical analyses were appropriate (e.g., regression analyses were used).
Let’s further say that our second research example had slightly less sufficient methodology. Although the number of participants in the two samples was high enough (N1 = 453; N2 = 488), the number of missing values was low, and statistical analyses were appropriate (descriptive statistics), the authors failed to report how they recruited their participants and whether they controlled for any confounders.
Let’s say that these authors also failed to provide you with more information via email. Finally, let’s assume that our third research example also had sufficient methodology, with a sufficiently large sample size for a qualitative investigation (N = 30), high sample representativeness (participants with different backgrounds, coming from different boat communities), and sufficient analyses (thematic analysis).
Note that, since this was a qualitative investigation, there is no need to evaluate the number of missing values and the use of confounders.
We would conclude that the secondary data from our first research example has a high quality. Data was recently collected by professionals, the employed measures were both reliable and valid, and the methodology was more than sufficient. We can be confident that our new research question can be sufficiently answered with the existing data. Thus, the data set for our first example is ideal.
The two secondary data sets from our second research example seem, however, less than ideal. Although we can answer our research questions on the basis of these recent data sets, the data was collected by an unprofessional source, the reliability and validity of the employed measure is uncertain, and the employed methodology has a few notable drawbacks.
Finally, the data from our third example seems sufficient both for answering our research question and in terms of the specific evaluations (data was collected recently by a professional source, semi-structured interviews were well made, and the employed methodology was sufficient).
The final question to ask is: “what can be done if our evaluation reveals the lack of appropriateness of secondary data?”. The answer, unfortunately, is “nothing”. In this instance, you can only note the drawbacks of the original data set, present its limitations, and conclude that your own research may not be sufficiently well grounded.
Your first sub-step here (if you are doing quantitative research) is to outline all variables of interest that you will use in your study. In our first example, you could have at least five variables of interest: (1) women’s nationality, (2) anxiety levels at the beginning of pregnancy, (3) anxiety levels at three months of pregnancy, (4) anxiety levels at six months of pregnancy, and (5) anxiety levels at nine months of pregnancy. In our second example, you will have two variables of interest: (1) participants’ nationality, and (2) the degree of interest in going to Greece for a summer vacation. Once your variables of interest are identified, you need to transfer this data into a new SPSS or Excel file. Remember simply to copy this data into the new file – it is vital that you do not alter it!
Once this is done, you should address missing data (identify and label them) and recode variables if necessary (e.g., giving a value of 1 to German participants and a value of 2 to British participants). You may also need to reverse-score some items, so that higher scores on all items indicate a higher degree of what is being assessed.
Most of the time, you will also need to create new variables – that is, to compute final scores. For instance, in our example of research on anxiety during pregnancy, your data will consist of scores on each item of the State Anxiety Inventory, completed at various times during pregnancy. You will need to calculate final anxiety scores for each time the measure was completed.
Your final step consists of analysing the data. You will always need to decide on the most suitable analysis technique for your secondary data set. In our first research example, you would rely on MANOVA (to see if women of different nationalities experience different stress levels at the beginning, at three months, at six months, and at nine months of pregnancy); and in our second example, you would use an independent samples t-test (to see if interest in Greek tourism differs between Germans and Britons).
The process of preparing and analysing a secondary data set is slightly different if your secondary data is qualitative. In our example on the reasons for living on boats, you would first need to outline all reasons for living on boats, as recognised by the original qualitative research. Then you would need to craft a questionnaire that assesses these reasons in a broader population.
Finally, you would need to analyse the data by employing statistical analyses.
Note that this example combines qualitative and quantitative data. But what if you are reusing qualitative data, as in our previous example of re-coding the interviews from our study to discover the language used when describing transient lifestyles? Here, you would simply need to recode the interviews and conduct a thematic analysis.

This article covers secondary research's dissertation significance, its role in building strong arguments, and selecting suitable data sources.
What is secondary research .
Secondary research uses existing sources to grasp a topic. It involves studying studies, articles, newspapers, and books. It's quicker than primary research, skipping data collection to focus on existing sources.
Secondary sources , often by expert researchers, offer thorough coverage, benefiting from their primary research and field expertise.
Secondary research is essential for any dissertation because it gives students the opportunity to draw on existing knowledge and build on the work of other scholars without having to conduct their original experiments or surveys.
By using secondary research instead of conducting original experiments or surveys, students can save time while still being able to access reliable information on their chosen topics.
Secondary sources broaden students' scope beyond just primary materials, enhancing argument strength. This integrates current literature with past expert findings for more robust dissertations.

Unlike primary research, which can be both time-consuming and expensive, secondary research relies on existing data that is readily available. This eliminates the need for data collection and expensive surveys.
Secondary research offers greater consistency than primary research, as the initial researcher addresses potential biases. This reduces variables, facilitating accurate conclusions. Moreover, secondary research can unveil unnoticed patterns, enhancing comprehension of the subject.
Finally, secondary research grants access to expert insights beyond your primary study group, enriching your dissertation and enhancing its credibility among academic peers.
Crafting an effective dissertation can be complex, but the right data sources could make all the difference. To help select quality information for your research needs, consider taking these key steps to ensure accuracy and thoroughness in writing. To better understand the use of secondary research and secondary data, study the Secondary Research Dissertation examples.

Secondary research is a research method that contains using already existing information. Existing information is summarized and organized to increase the overall efficiency of research. Secondary data collection includes research material published in study reports and similar documents. These PhD Secondary Data Collection Resources can be made available by libraries, websites, information obtained from already filled in reviews etc. Some government and non-government interventions also store data, that can be used for study purposes and recovered. Unlike primary research where data is composed first hand by governments or businesses, they can employ a third party to gather data on their behalf in the Methodology of Secondary Data Collection .
1. frame your research question.
Secondary research starts exactly like any research: by building up your research question(s). For the Research Proposal , you are frequently given a particular research question by your guide. Yet, for most different sorts of examination, and mainly if you are doing your alumni proposition, you need to show up at a research question yourself. The initial step here is to determine the overall research territory where your examination will fall. Whenever you have distinguished your overall theme, your following stage comprises of perusing existing documents to see whether there is a break in the writing that your research can fill.
In the wake of looking into the writing and indicating your Research Methodology Secondary Data addresses, you may choose to depend on secondary data. You will do this if you find that past data would be entirely reusable in your research, accordingly assisting you with responding to your examination question all the more altogether. In any case, how would you find if some past data could be valuable for your research? You do this through inspecting the writing on your subject of interest. You will recognize different scientists, associations, organizations, or examination focuses on investigating your research theme during this interaction. Someplace there, you may find a helpful secondary data index. At that point, you need to contact the first creators and request consent to utilize their data. (Note, in any case, that this happens just if you depend on outside wellsprings of secondary research. If you are doing your examination inside (i.e., inside a specific association), you don’t have to look through the writing for a secondary data index – you can reuse some previous data gathered inside the actual association.) For any situation, you need to guarantee that a secondary data index is a solid match for your research question. Whenever you have set up that, you need to determine why you have chosen to depend on PhD Secondary Data collection services .
While assessing secondary data, you first need to recognize the point of the first investigation. It is significant because the first creators’ objectives will have affected a few significant parts of their examination, including their populace of decision, test, utilized estimation devices, and the research’s general setting. During this progression, you additionally need to give close consideration to any distinctions in PhD Research Methodology Secondary Data inquiries between the first examination and your examination for quantitative secondary data collection methods. As we have discussed already, you will frequently find that the first investigation had an alternate examination question as a top priority. It is significant for you to indicate this distinction in Secondary Data Collection Methods.
A further advance in assessing a secondary data index is to ask yourself who has gathered the data. To what organization were the creators partnered? Were the first creators sufficiently proficient at confiding in their research? For the most part, you need to acquire this data through short online pursuits.
On the off chance that the investigation on which you are basing your examination was directed expertly, you can hope to approach all the fundamental data concerning this research. Unique creators ought to have archived all their example qualities, measures, methods, and conventions. This data can be acquired either in their last examination report or through reaching the creators straightforwardly. It is significant for you to understand what sort of data was gathered, which measures were utilized, and whether such actions were reliable and legitimate. You also need to remove the kind of data concluded, particularly the data pertinent for your research.
While assessing secondary data, you ought to likewise note when the data was gathered. The purpose behind this is straightforward: if the data was serene quite a while past, you might presume that it is obsolete. Furthermore, on the off chance that the information is outdated, at that point, why reuse it? In a perfect world, you need your secondary data gathered inside the most recent five years.
While assessing a secondary data collection’s nature, the utilized approach’s assessment might be the critical advance. We have just noticed that you need to evaluate the dependability and legitimacy of used measures. Moreover, you need to assess how the example, regardless of whether the standard was adequately enormous. Suppose the example was illustrative of the populace, if there were any missing reactions on utilized measures, whether confounders were slow for, and whether the utilized factual investigations were suitable. Any disadvantages in the first technique may restrict your examination too.
Having considered all the things illustrated in the means above, what would you be able to finish up concerning the nature of your secondary data collection? Once more, how about we think about our three models. We would reason that the secondary data from our first examination model has a high calibre. As of late gathered by experts, the utilized measures were both dependable and substantial.
During the secondary data assessment measure, you will acquaint yourself with the first research. Your subsequent stage is to set up a secondary data index. Your last advance comprises of dissecting the data. You will consistently have to settle on the most appropriate investigation strategy for your secondary data index for Qualitative Secondary Data in Research Methodology.
The process of preparing and analyzing a secondary data set is slightly different if your secondary data is qualitative. So simple that PhD assistance has explained how to do it entirely in just four steps and provides Secondary Quantitative Data Collection .

Introduction.
The methodology section will be the chapter that you write following on from your literature review . After you have researched and discovered the gap in the available literature, it is possible for you to create ideas for your proposed research.
In your research proposal , you will have had a suggested methodology where you would have given ideas about how to approach the research: this would have been either through a primary data approach or through collecting secondary data .
Primary data is any form of evidence that you collect yourself through your own research in the form of surveys, interviews, questionnaires, focus groups, observations, experiments. Primary data collection methods does not involve the collection of data from other researchers’ work and their studies.
Collecting secondary data is the collection of evidence from previous researchers’ work. An example could be focusing on another researchers’ experiment and using their findings as a basis for your dissertation. An example could be collecting the findings from two different experiments and comparing the findings of these studies in relation to the question posed.
Once you have decided what type of data you will be collecting, you will then need to determine whether the data being collected is qualitative or quantitative as this will have an impact on the analysis of your research.
Quantitative research only produces results on the specific issue that is being investigated and uses statistical, mathematical and computational programmes.
A closed-ended questionnaire would be analysed using quantitative research if the researcher merely computed the results and produced a series of comments as to the percentages of respondents who gave specific answers. A common programme by which to analyse quantitative research is SPSS.
Qualitative research tends to be used more in the social sciences and arts and is when a research seeks to ask ‘why’ and ‘how’ something has happened and explains the reasons with recourse to empirical mathematical models.
Within primary research that uses qualitative research, small focus groups can often be employed.
An open-ended questionnaire that collates and assesses a range of verbal responses would be analysed using qualitative techniques as the answers given do not lend themselves to being processed in the manner described above relating to closed questionnaires.
Another option is through a mixed methods approach, which would be the collection of both primary and secondary data.
In a dissertation where one is assessing, for instance, the effects of flooding in the Wirral peninsula, it is likely that all the research techniques mentioned above would be used.
Secondary data would be used through a literature review. Closed-ended questionnaires could be analysed using a statistical panel and interviews with experts would be commented upon with reference to existing literature.
Accordingly, both primary and secondary research techniques would be utilised as well as qualitative and quantitative mechanisms.
You should begin your methodology with a brief introduction to the chapter, this should also include relaying the aims of the study. Following on from this, it is best to start by defining and choosing the research paradigm for the dissertation.
Research paradigms – there are 4 main approaches to research. These are positivism, interpretivism (also known as constructivism), post-positivism and critical theory.
Once you have defined your research philosophy, the next step would be to identify your research approach and instrument.
Research approach – This can be separated by two types:
Deductive research is the approach you would take if you had hypotheses that were being tested, then you would be using a deductive research approach.
Inductive research is when there is a set of observations and a theory is developed to explain those observations or any patterns that are amongst those observations.
Following on from this, you would then be expected to discuss your chosen data collection method along with stating if the research is either quantitative or qualitative. When writing about key terms i.e. primary data; it is always best to define, explain and justify why.
In so doing, you should also note (briefly) what is inappropriate about the other approaches as well as the ways in which you have overcome any negatives that are associated with your approach.
If your chosen methodology is the collection of primary data, the next step would be the describe and explain the sampling and participant selection.
Here you would need to describe and explain the chosen sampling method along with the number of participants selected. It is always good to include how you contacted the participants and recruited them for the study.
If you are using primary data, it is always crucial to include a sub-chapter of the work that discusses any ethical concerns and considerations that arose due to your chosen methodology.
For both primary and secondary data, it is necessary to include a sub-section on the data analysis that will be used to collate and analyse the data gathered in the research.
Here you will discuss how you intend to analyse the data and why you have chosen this analytical technique.
Whichever approach you use it is important that you justify your decision and that you do so via reference to existing academic works – and writing only in the third person.
As with the background section of your dissertation, your methodology section needs to be grounded in existing academic opinion.
The following books provide not only an overview of methodological approaches (and the strengths and weaknesses associated with each) but are also the sorts of books that your lecturers may expect to see referenced within your methodology section, depending on the type of course you are doing.

You do not need to read them all, but you should show (using appropriate and limited direct quotation for extra marks) at least some knowledge of the arguments contained within these books. For an undergraduate dissertation it would be good practice to include at least five of these books (or their equivalent – depending upon what is available within your library) in your bibliography.

Secondary research is a useful strategy to obtain data and support your ideas when conducting research for your dissertation. It will always be challenging to write a large project like a dissertation all by yourself (professional essay service, 2019). In dissertation secondary research, a specific study subject or topic is investigated utilizing published data sources, such as books, journals, and internet databases. Although conducting secondary research may seem simple, it necessitates a systematic approach to guarantee that you locate and utilize the most relevant and trustworthy sources.
One of the main purposes of secondary research is to thoroughly grasp the body of material that already exists on a certain topic. It frequently serves as a framework for the study and helps contextualize a research topic or hypothesis. Researchers can also find gaps in the literature and areas that need more inquiry by using secondary sources.
Another purpose of secondary research is, secondary research can provide useful insights into the research methodology and analytical techniques employed by other researchers, which can inform the design and implementation of the current study.
Dissertation secondary research can be split into two major categories: qualitative and quantitative. While quantitative research is used to gather and analyze numerical data, qualitative research examines individuals’ or groups’ subjective experiences and viewpoints. Other sorts of secondary research fall under these broad categories, including:
literature review: A literature review critically evaluates the body of writing already written about a certain subject. It entails locating, analysing, and synthesizing the pertinent literature to present a thorough overview of the subject field.
Meta-analysis: A meta-analysis is a statistical procedure that combines the findings of several studies to produce a more accurate assessment of the magnitude of an intervention’s or variable’s impact.
Systematic review: Reviewing the literature on a certain topic systematically is a disciplined and organized process in PhD dissertation . It entails formulating an inclusion and exclusion criterion, creating a research topic, then looking up and synthesizing the pertinent literature.
Content analysis: It is a technique for examining written or visual content to spot themes, patterns, and trends.
Historical analysis: Historical analysis is the process of looking at old records or artifacts to understand historical occurrences or social phenomena.
Recognizing these types of overconfidence bias can help individuals become more self-aware and take steps to reduce their impact on decision-making.
Compared to primary research methods, there are numerous advantages of secondary research. First off, you can easily find dissertation help in UK . Second, because secondary research includes analyzing existing data rather than gathering new data, it frequently takes less time and costs less money than primary research. Second, by using a variety of sources and disciplines, secondary research can provide a topic with a broader perspective. Thirdly, by conducting secondary research, scholars can steer clear of duplicating prior findings or committing the same errors. Finally, by highlighting areas that need additional research, secondary research can serve as a foundation for subsequent studies.
Secondary research has several drawbacks despite its benefits. First off, because it depends on the veracity and validity of the material that is already available, secondary research is frequently prone to bias. Second, the calibre and amount of the available types of secondary data may be a constraint for secondary research.
Here is the secondary research process in 4 steps describes briefly.
You must choose pertinent dissertation secondary sources after defining your study question. You can conduct secondary research using a range of sources, such as books, journals, online databases, and government papers. Finding answers to open-ended issues as a way of learning and/or developing new knowledge is a part of the research, in addition to simply acquiring information (Goddard, Melville, 2001).
There are many different search techniques you can employ to find relevant dissertation secondary sources. Using keywords related to your research subject to search internet databases and library catalogs is a typical strategy. You can also search for books and articles that are mentioned in the materials you’ve already found.
After you have found probable sources, you must assess them to see if they are pertinent, trustworthy, and reliable. You can assess sources using a variety of factors, such as the author’s qualifications, the source’s publication date, and its reputation.
It’s crucial to remember that not all sources are created equal while examining them during creating dissertation using only secondary data. Other sources could be out-of-date or irrelevant to your research issue, while some could be prejudiced or unreliable. A source’s context should also be taken into account because it may have an impact on its credibility and applicability.
Analysis and synthesis of the sources you have chosen are the last steps in secondary research. This entails carefully reading each source and making notes on the most important conclusions, points, and supporting details.
You should search for trends and connections among your sources as you study them when you are creating dissertation using only secondary data. Additionally, you should evaluate how the sources you have chosen support or refute your research question and thesis.
You can start combining your sources into a coherent argument after you have evaluated them. This entails determining the key ideas and points that are supported by your sources and utilizing them to strengthen your own argument.
A crucial step in writing a dissertation is conducting secondary research. You can create a compelling argument for your position and prove your subject-matter expertise by using a methodical strategy to locate, assess, and analyze information. You can do efficient secondary research that will aid in the creation of your dissertation by establishing your research question, discovering pertinent sources, assessing these sources, and analyzing and synthesizing your findings.
In a dissertation, secondary research entails acquiring data from already published sources, including scholarly works, governmental papers, statistical data, and other publically accessible sources or getting secondary data collection help . This research technique entails going through and examining the information that has previously been gathered by others. Secondary research can shed light on a subject and serve to put primary research findings into context. It can also support the development of research questions by highlighting knowledge gaps
The precise research issue, the information and resources at hand, and the appropriate secondary research methodology dissertation example will all be determined by these factors. However, completing a literature review is a typical instance of secondary research. A researcher might do a literature review to find studies that have looked into the usefulness of cognitive behavioural therapy (CBT) for treating depression, for instance. The literature study may involve reading books on the subject, examining government reports and other publically accessible sources of information, and searching academic databases for pertinent publications.

Find out what secondary data is – as opposed to primary data – and how to go about collecting and using it.
What is secondary data & archival material, using published data sets, using archival data, secondary data as part of the research design, gaining access to, and using, archives, primary & secondary data.
All research will involve the collection of data. Much of this data will be collected directly through some form of interaction between the researcher and the people or organisation concerned, using such methods as interviews, focus groups, surveys and participant observation. Such methods involve the collection of primary data, and herein lies the opportunity for the researcher to develop and demonstrate the greatest skill.
However sometimes the researcher will use data which has already been collected for other purposes – in other words, he or she is going to an existing source rather than directly interacting with people. The data may have been:
Either way, such material is termed secondary data.
Rather confusingly, the latter form of secondary data is also referred to as primary source material.
"Primary resources are sources that are usually created at the time of an event. Primary resources are the direct evidence or first hand accounts of historical events without secondary analysis or interpretation." (York University Libraries Archival Research Tutorial)
This distinguishes them from secondary sources which describe, analyse and refer to the primary sources.
The above definitions and distinctions can be described diagrammatically as follows:
Secondary data is found in print or electronic form, if the latter, on CD-ROM, as an online computer database, or on the Internet. Furthermore, it can be in the form of statistics collected by governments, trade associations, organisations that exist to collect and sell statistical data, or just as plain documents in archives or company records.
A crucial distinction is whether or not the data has been interpreted, or whether it exists in raw form.
Because interpreted data will have been collected deliberately, the plan behind its collection and interpretation will also have been deliberate – that is, it will have been subjected to a particular research design.
By contrast, raw data will not have been processed, and will exist in its original form. (See " Using archival data " section in this guide.)
There are various reasons for using secondary data:
You should pay particular attention to the place of secondary documents within your research design. How prominent a role you give to this method may depend on your subject: for example, if you are researching in the area of accounting, finance or business history, secondary documentary sources are likely to play an important part. Otherwise, use of secondary data is likely to play a complementary part in your research design. For example, if you are studying a particular organisation, you would probably want to supplement observation/interviews with a look at particular documents produced by that organisation.
In " Learning lessons? The registration of lobbyists at the Scottish parliament " ( Journal of Communication Management , Vol. 10 No. 1), the author uses archival research at the Scottish parliament as a supplementary research method (along with the media and focus groups), his main method being interviews and participant observation of meetings.
This point is further developed in the " Secondary data as part of the research design " section of this guide. Reasons for using the different types of secondary data are further developed in the individual sections.
NB If you are doing a research project/dissertation/thesis, check your organisation's view of secondary data. Some organisations may require you to use primary data as your principle research method.
The advantages of using secondary data are:
The disadvantages of secondary data collection are:
As discussed in the previous section, these are sources of data which have already been collected and worked on by someone else, according to a particular research design. Other points to note are:
There are a number of points to consider when using data sets, some practical and others associated with the research design (yours and theirs).
Practical considerations relate to cost and use:
Research considerations include:
And finally...
Producers of published secondary data include:
Where to find such information? The key is to have a very clear idea of what it is you are trying to find: what particular aspects of the research question are you attempting to answer?
You may well find sources listed in your literature review, or your tutor may point you in certain directions, but at some point you will need to consult the tertiary literature, which will point you in the direction of archives, indexes, catalogues and gateways. Your library will probably have Subject Guides covering your areas of interest. The following is a very basic list:
Archival, or documentary secondary data, are documentary records left by people as a by product of their eveyday activity. They may be formally deposited in an archive or they may just exist as company records.
Historians make considerable use of archival material as a key research technique, using a wide range of personal documents such as letters, diaries, household bills, which are often stored in some sort of formal "archive".
Business researchers talk about "archival research" because they use many of the same techniques for recording and analysing information. Companies, by their very nature, tend to create records, both officially in the form of annual reports, declarations of share value etc., and unofficially in the e-mails, letters, meeting minutes and agendas, sales data, employee records etc. which are the by-product of their daily activities.
If you are studying a business and management related subject, you may make use of archival material for a number of reasons:
In " Financial reporting and local government reform – a (mis)match? " ( Qualitative Research in Accounting & Management , Vol. 2 No. 2), Robyn Pilcher uses archival research – "Data was obtained from annual reports provided electronically to the DLG and checked against hard copies of these reports and supporting notes" – and interviews as exploratory research to investigate use of flawed financial figures by political parties, before carrying out a detailed examination of a few councils.
" Coalport Bridge Tollhouse, 1793-1995 " ( Structural Survey , Vol. 14 No. 4) is a historical study of this building drawing on such documents as maps, plans, photos, account books, meeting minutes, legal opinions and census records.
As distinct from published data sets, you will have to record and process the data yourself, in order to create your own data set.
Sometimes this archival material will be stored in "official" archives, such as the UK Public Record Office. Mostly however, it will be company specific, stored in official company archives or perhaps in smaller collections in individual departments or business units. Records can exist in physical or electronic form – the latter commonly on the company intranet.
Whatever the company's archiving policy, there is no doubt that businesses provide a rich source of data. Here is a (non exhaustive) list of the forms that data can take:
Management Information Systems can hold a considerable amount of data. For example, the following HR records may be held:
Source: Peter Kingsbury (1997), IT Answers to HR Questions , CIPD.
The media (newspapers, magazines, advertisements, television and radio programmes, books, the Internet) can also throw valuable light on events, and media sources should not be ignored.
There are a number of points to consider when using archival material:
In " Participatory group observation – a tool to analyse strategic decision-making " ( Qualitative Market Research , Vol. 5 No. 1), Christine Vallaster and Oliver Koll highlight the benefit of multiple methods for studying complex issues, it being thus possible to supplement the weaknesses of one method with the strengths of another and study a phenomenon from a diversity of views, and achieve a high degree of validity. In the case in question, archival research was used to analyse documents (organisation charts, company reports, memos, meeting minutes), and whilst the limitations in terms of incompleteness, selectivity, and not being authored by interviewees were acknowledged, so was their supporting value to interviews, and the same textual analysis method was used for both methods.
We have already mentioned, as part of our discussion of the two main types of secondary data, some considerations in respect to how they are used as part of the research. In this section, we shall look more generally at how secondary data can fit in to the overall research design.
Researchers take different views of the facts they are researching. For some, facts exist as independent reality; others admit the possibility of interpretation by the actors concerned. The two views, and their implication for the documents and data concerned, can be summed up as follows:
Some examples would be:
Reliability and validity is important to any research design, and an important consideration with secondary data is the extent to which it relates to the research question, in other words how reliably it can answer it. You need to consider the fit very carefully before deciding to proceed. Some questions which may help here are:
In the case of published data, you will be able to make a judgement by looking at its provenance: does it come from the government, or from a reputable commercial source? The same applies to the Internet – what is the source? Look for publisher information and copyright statements. How up to date is the material?
You also need to make intrinsic judgements, however: what is the methodology behind the survey, and how robust is it? How large was the sample and what was the response rate?
There are fewer obvious external measures you can use to check unpublished, archival material: that from businesses can be notoriously inconsistent and inaccurate. Records can be incomplete with some documents missing; sometimes, whole archives can disappear when companies are taken over. In addition, some documents such as letters, reports, e-mails, meeting minutes etc. have a subjective element, reflecting the view of the author, or the perceived wishes of the recipient. For example, meeting minutes may not reflect a controversial discussion that took place but only the agreed action points; a report on sales may be intended to put a positive spin on a situation and disguise its real seriousness. It helps when assessing reliability to consider who the intended audience is.
If you are using media reports, be aware that these may only include what they consider to be the most pertinent points.
One of the biggest problems with secondary data is to do with the measurements involved. These may just not be the same as the ones you want (e.g. sales given in revenue rather than quantity), they may deliberately be distorted (e.g. non recording of minor accidents, sick leave etc.), or they may be different for different countries. If the measures are inexact, you need to take a view as to how serious the problem is and how you can address it.
Does the data cover the time frame, geographical area, and variable in which you are interested? For example, if you are studying a particular period in a company, do you have meeting minutes to cover that period, or do they stop/start at a time within the boundaries of that period? Do you have the sales figures for all the countries your are interested in, and all the product types?
You can greatly increase the validity and reliability of your use of secondary data if you triangulate with another research method. For example if you are seeking insights into a period of change within a company, you can use documentary records to compare with interviews with key informants.
" Leading beyond tragedy: the balance of personal identity and adaptability " ( Leadership & Organization Development Journal , Vol. 26 No. 6) is a case study of the Norwegian company Wilhelmson's Lines loss of key employees in a plane crash, and uses archival research along with on-site interviews and participant observation as the tools of case study analysis.
" The human resource management practice of retail branding: an ethnography within Oxfam Trading Division " ( International Journal of Retail & Distribution Management , Vol. 33 No. 7) uses an ethnographic approach and includes scanning the company intranet along with participant observation and interviews.
Documentary data can be used as part of a qualitative or quantitative research design.
Much data, whether from company archives or from published data sets, is statistical, and can therefore be used as part of a quantitative design, for example how many sales were made of a particular item, what were reasons for absenteeism, company profitability etc.
One way of using secondary data in quantitative research is to compare it with data you have collected yourself, probably by a survey. For example, you can compare your own survey data with that from a census or other published survey, which will inevitably have a much larger sample, thereby helping you generalise, and/or triangulate, your findings.
Textual data can also be used qualitatively, for example marketing literature can be used to as backup information on marketing campaigns, and e-mails, letters, meeting minutes etc. can throw additional light on management decisions.
Content analysis is often quoted as a method of analysis: this involves analysing occurrence of key concepts and ideas and either draw statistical inferences or carry out a qualitative assessment, looking at the main themes that emerge.
Archives may be found in national collections, such as the UK's Public Record Office, or as smaller collections associated with national, local or federal government organisations, academic libraries, professional or trade associations, or charities; they may also be found in companies. The latter are generally closely controlled; the former are most likely to be publically available. This page gives a brief overview of how to gain access to archival collections, and what you can expect when you get there.
An archival collection, even an open one, is not like a library where you can just turn up. You need to establish opening hours, and then make arrangements to visit.
It is best to write ahead explaining:
In order to be clear about point 2, you will need to know not only the precise scope of your research but also how this particular collection can help you. You will therefore need to spend time researching (perhaps more than one) collection, so make sure that this is allowed for in your research plan.
You also need to understand the key difference between libraries and archives:
Bibliographic databases are good sources for finding archival collections: you can search by subject, keyword, personal or geographical name. Whilst not containing records of each item, catalogue records of archival collections are generally lengthier than for published materials and may include a summary of materials contained in the collection.
More detailed information about the collection, usually at the level of the box or folder, is found in Finding Aids .
You can find suitable databases through your library's Subject Guides.
As indicated above, commercial archival or document collections are more tightly controlled than public ones, access to which will depend upon a clearly stated request and proof of identity.
Commercial sources, by contrast, may require more negotiation, and more convincing, because of the perceived sensitivity of their material and the fact that they exist for their customers and shareholders, and not as an archival collection. Companies understandably count the opportunity cost of time spent "helping a researcher with their enquiries", not to mentioning opening up possibly sensitive documents to the prying eyes of an outsider.
This can cause problems to the researcher because if the research project is based on one or a few companies, if access is denied then the overall validity of the research will be prejudiced. Given the likelihood that other research methods, such as interview, survey etc. are also being used, it is best to approach access in the widest sense, and stress the benefits to the organisation, the credibility of the researcher, and assurance of confidentiality.

Secondary research, also known as a literature review , preliminary research , historical research , background research , desk research , or library research , is research that analyzes or describes prior research. Rather than generating and analyzing new data, secondary research analyzes existing research results to establish the boundaries of knowledge on a topic, to identify trends or new practices, to test mathematical models or train machine learning systems, or to verify facts and figures. Secondary research is also used to justify the need for primary research as well as to justify and support other activities. For example, secondary research may be used to support a proposal to modernize a manufacturing plant, to justify the use of newly a developed treatment for cancer, to strengthen a business proposal, or to validate points made in a speech.
Because secondary research is used for so many purposes in so many settings, all professionals will be required to perform it at some point in their careers. For managers and entrepreneurs, regardless of the industry or profession, secondary research is a regular part of worklife, although parts of the research, such as finding the supporting documents, are often delegated to juniors in the organization. For all these reasons, it is essential to learn how to conduct secondary research, even if you are unlikely to ever conduct primary research.
Secondary research is also essential if your main goal is primary research. Research funding is obtained only by using secondary research to show the need for the primary research you want to conduct. In fact, primary research depends on secondary research to prove that it is indeed new and original research and not just a rehash or replication of somebody else’s work.
Using secondary data can be a good alternative to collecting data directly from participants (primary data), removing the need for face-to-face contact.
Secondary data relating to living human subjects often requires ethical approval depending on the source and nature of the data. The extent to which the ethical review application form must be completed also depends on the source and nature of the data.
This guidance covers some of the ethical issues relating to use of secondary data and how this impacts the ethical application process.
Ethical approval is required for projects where secondary data includes personal data - data that relates to identifiable living persons.
When data relates to deceased human subjects, ethical approval is required if the data includes either:
And where this data identifies, or could identify, either the deceased individual or others.
Among the reasons ethical review is required is because:
Data which are completely and robustly anonymised do not contain personal data and so ethical review and approval is usually not required.
For the avoidance of doubt, this means data that are already anonymised rather than data received in identifiable or pseudonymised form and then anonymised by the researcher.
However, there are scenarios involving anonymised data where ethical approval may be required (discuss with your School ethics committee if you are unsure):
If the data source requires assurances that the project has undergone ethical review or evidence that use of the data is legitimate, an ethical review application can be submitted.
If the data source requires a:
If the data involves or originates from the NHS or health and social care, see the Research involving the NHS page.
If the data could be used to re-identify individuals, then an ethical review application may be needed - consider the items of data you will be working with and whether this is a risk.
For example:
Combined data - combining data can lead to re-identification of individuals, particularly if data is linked at an individual level by matching unique reference numbers or data points.
Rare, unusual, or low number data – rare or unique data, such as that relating to unusual characteristics or rare health conditions, are difficult to truly anonymise as there often few individuals with those characteristics or conditions.
Reasonable means – GDPR suggests that the risk of identification, researchers should consider ‘means reasonably likely to be used’, accounting for factors such as costs and time involved and available technology.
If there are additional ethical considerations, an ethical review application can be submitted. For example, if data raises concerns around:
See the section below on ethical considerations.
Secondary data – internal datasets
Secondary datasets may sometimes be sourced from the within the University i.e. data collected as part of previous projects within a School. It is important to consider whether re-use of this data is in line with the original ethical approval and the consent given by participants. An ethical amendment may be required for both the original ethical approval to allow the data to be shared AND a new ethical review application for the new research project (if sufficiently different).
Internally sourced data should still be acknowledged and appropriately referenced, and the same considerations given as to other secondary data sources such as around access and permissions, data management and confidentiality. Researchers should also consider whether using this type of secondary data is appropriate for their needs (i.e. whether it meets the requirements for an academic research project).
Secondary data - large quantitative datasets
A commonly used source of secondary data are large quantitative data sets such as census data, health data, household surveys and market research.
There are several sources that can give access to these types of data and what is required to access them varies by source and by the nature of the data, for example:
Sometimes more sensitive datasets can only be accessed via a secure web portal and no local copies retained.
Secondary data - qualitative and mixed-methods data
Secondary qualitative data is less common, largely due to the difficulty in anonymising qualitative data. However, there are sources of secondary qualitative data including the UK Data Service and library data such as oral histories, diaries and biographies.
Secondary data - biological data
There are several resources for access to biological data including human-related data. Use of biological data and bioinformatics is a wide are with several ethical concerns around confidentiality, implications of research into DNA and genomics, bias and profiling, the sensitivity of identifying risk levels related to disease. Researchers planning research involving biological data or bioinformatics should consult with disciplinary guidelines and organisations and colleagues with specific expertise. If using secondary data of this type, researchers must ensure they do so in accordance with the requirements of the data sources. Researchers should also ensure that they check if any NHS ethical approval, governance or R&D approvals are required .
Access, permissions and consent
Access to secondary data must always be used in accordance with the requirements of the data source, GDPR and the common law duty of confidentiality. Secondary data must always be appropriately referenced and acknowledged. Researchers should always act in accordance with the Principles of Good Research Conduct , even when working with secondary data.
Researchers should check whether their use is in line with the consent originally obtained from participants and seek assurances on this from the data source.
Where data is obtained in anonymous form, researchers should be conscious of the risk of de-anonymising data through triangulation of several data points or sets.
While there are open access datasets that are freely available, it is common that there are conditions and requirements put in place by the data source or controller around who can access the data and how it is used. For example, this might include:
In the latter examples, where there is more complex requirements and the data source is providing a service such as preparing and moderating access, this may incur costs that would need to be factored into researchers plans and budgets.
Ethical issues to consider.
The ethical application form includes an early filter question on use of secondary sources. This means that if researchers are using secondary data with no additional ethical issues they can skip to the end of the form – the declarations section. If, however, there are ethical issues, researchers should describe these and how they will be mitigated in the ‘Ethical Considerations’ free text field later in the form.
If data are particularly sensitive, or it is required by the data source, researchers may wish to complete the Data Management section of the ethical review application form (Word) or a separate data management plan .
When making an application for ethical approval of research using secondary data, researchers should consider:
You may find parts of the UK Government's Data Ethics Framework useful for exploring some of the potential issues.

When does the secondary use of existing data not require review?
Secondary Research Examples. 1. Literature Review. A literature review summarizes, reviews, and critiques the existing published literature on a topic. Literature reviews are considered secondary research because it is a collection and analysis of the existing literature rather than generating new data for the study.
Types of secondary data are as follows: Published data: Published data refers to data that has been published in books, magazines, newspapers, and other print media. Examples include statistical reports, market research reports, and scholarly articles. Government data: Government data refers to data collected by government agencies and departments.
Introduction. Secondary data analysis is a valuable research approach that can be used to advance knowledge across many disciplines through the use of quantitative, qualitative, or mixed methods data to answer new research questions (Polit & Beck, 2021).This research method dates to the 1960s and involves the utilization of existing or primary data, originally collected for a variety, diverse ...
Secondary research is a research method that uses data that was collected by someone else. In other words, whenever you conduct research using data that already exists, you are conducting secondary research. On the other hand, any type of research that you undertake yourself is called primary research. Example: Secondary research.
Use . Virtually all research will use secondary sources, at least as background information. Often, especially at the postgraduate level, it will also use primary sources - secondary and/or primary data. The engagement with primary sources is generally appreciated, as less reliant on others' interpretations, and closer to 'facts'.
Step 3: Design your research process. After defining your statement of purpose, the next step is to design the research process. For primary data, this involves determining the types of data you want to collect (e.g. quantitative, qualitative, or both) and a methodology for gathering them. For secondary data analysis, however, your research ...
as the bridge between the raw data you collect and the conclusions you draw. This stage of your research process is vital because it transforms data into meaningful insights, allowing you to address your research questions and hypotheses comprehensively. Proper analysis and interpretation not only validate your findings but also enhance the overall quality and credibility of your dissertation.
In a nutshell, secondary research is far more simple. So simple, in fact, that we have been able to explain how to do it completely in just 4 steps (see below). If nothing else, secondary research avoids the all-so-tiring efforts usually involved with primary research.

Secondary data would be used through a literature review. Closed-ended questionnaires could be analysed using a statistical panel and interviews with experts would be commented upon with reference to existing literature. Accordingly, both primary and secondary research techniques would be utilised as well as qualitative and quantitative mechanisms.

In dissertation secondary research, a specific study subject or topic is investigated utilizing published data sources, such as books, journals, and internet databases. Although conducting secondary research may seem simple, it necessitates a systematic approach to guarantee that you locate and utilize the most relevant and trustworthy sources.
Secondary qualitative data analysis can be a powerful method by which to gain insights that primary data analysis cannot offer. There is much literature using primary interview data, but often, the primary data represent either a small sample size or a limited regional pool.
