What is a Directional Hypothesis? (Definition & Examples)
A hypothesis test can either contain a directional hypothesis or a non-directional hypothesis: Directional hypothesis: The alternative hypothesis contains the less than ("<") or greater than (">") sign. This indicates that we're testing whether or not there is a positive or negative effect. Non-directional hypothesis: The alternative ...
Directional Hypothesis: Definition and 10 Examples
Directional Hypothesis Examples. 1. Exercise and Heart Health. Research suggests that as regular physical exercise (independent variable) increases, the risk of heart disease (dependent variable) decreases (Jakicic, Davis, Rogers, King, Marcus, Helsel, Rickman, Wahed, Belle, 2016). In this example, a directional hypothesis anticipates that the ...
Directional and non-directional hypothesis: A Comprehensive Guide
Directional hypotheses, also known as one-tailed hypotheses, are statements in research that make specific predictions about the direction of a relationship or difference between variables. Unlike non-directional hypotheses, which simply state that there is a relationship or difference without specifying its direction, directional hypotheses ...
Directional vs Non-Directional Hypothesis: Key Difference
In summary, a directional hypothesis makes a specific prediction about the direction of the relationship or difference, while a non-directional hypothesis suggests a relationship or difference without specifying the direction. The choice between the two depends on the research question, existing literature, and the researcher's objectives.
Research Hypothesis: Definition, Types, Examples and Quick Tips
Non-directional hypothesis: A non-directional hypothesis only claims an effect on the dependent variable. It does not clarify whether the result would be positive or negative. The sign for a non-directional hypothesis is '≠.' 3. Simple hypothesis. A simple hypothesis is a statement made to reflect the relation between exactly two variables.
A Practical Guide to Writing Quantitative and Qualitative Research
On the other hand, hypotheses may not predict the exact direction and are used in the absence of a theory, or when findings contradict previous studies (non-directional hypothesis).4 In addition, hypotheses can 1) define interdependency between variables (associative hypothesis),4 2) propose an effect on the dependent variable from manipulation ...
Sage Research Methods
A directional hypothesis is a prediction made by a researcher regarding a positive or negative change, relationship, or difference between two variables of a population. This prediction is typically based on past research, accepted theory, extensive experience, or literature on the topic. Key words that distinguish a directional hypothesis are ...
What is a Directional Hypothesis? (Definition & Examples)
Null Hypothesis (H 0): The sample data occurs purely from chance. Alternative Hypothesis (H A): The sample data is influenced by some non-random cause. A hypothesis test can either contain a directional hypothesis or a non-directional hypothesis: Directional hypothesis: The alternative hypothesis contains the less than ("") sign. This ...
Understanding Statistical Testing
Abstract. Statistical hypothesis testing is common in research, but a conventional understanding sometimes leads to mistaken application and misinterpretation. The logic of hypothesis testing presented in this article provides for a clearer understanding, application, and interpretation. Key conclusions are that (a) the magnitude of an estimate ...
The Research Hypothesis: Role and Construction
A hypothesis (from the Greek, foundation) is a logical construct, interposed between a problem and its solution, which represents a proposed answer to a research question. It gives direction to the investigator's thinking about the problem and, therefore, facilitates a solution. Unlike facts and assumptions (presumed true and, therefore, not ...
How to Write a Directional Hypothesis: A Step-by-Step Guide
In research, hypotheses play a crucial role in guiding investigations and making predictions about relationships between variables. ... A directional hypothesis is a statement that predicts the direction of the relationship between two variables. Unlike non-directional hypotheses, which simply state that there is a relationship between ...

5.2 - Writing Hypotheses. The first step in conducting a hypothesis test is to write the hypothesis statements that are going to be tested. For each test you will have a null hypothesis (H 0) and an alternative hypothesis (H a). When writing hypotheses there are three things that we need to know: (1) the parameter that we are testing (2) the ...
7.3: The Research Hypothesis and the Null Hypothesis
Non-Directional Research Hypothesis. A non-directional hypothesis states that the means will be different, but does not specify which will be higher. In reality, there is rarely a situation in which we actually don't want one group to be higher than the other, so we will focus on directional research hypotheses.
Hypotheses; directional and non-directional
The directional hypothesis can also state a negative correlation, e.g. the higher the number of face-book friends, the lower the life satisfaction score ". Non-directional hypothesis: A non-directional (or two tailed hypothesis) simply states that there will be a difference between the two groups/conditions but does not say which will be ...
Research Hypothesis In Psychology: Types, & Examples
A research hypothesis, in its plural form "hypotheses," is a specific, testable prediction about the anticipated results of a study, established at its outset. ... A non-directional hypothesis, also known as a two-tailed hypothesis, predicts that there is a difference or relationship between two variables but does not specify the direction of ...
Data analysis: hypothesis testing: 4.3 One-sided tests
A directional hypothesis is a type of research hypothesis that aims to predict the direction of the relationship or difference between two variables. Essentially, it specifies the anticipated outcome of a study prior to the collection of data. For example, a directional hypothesis might propose that a marketing campaign will increase product ...
PDF Step 6 Writing Your Hypotheses
The research hypothesis can be written in a directional or non-directional manner. Directional (one tailed) - specifics the direction of the expected relationship (e.g., H0: µ1 µ2, HA: µ1 > µ2 ). When you test the null hypothesis, you are testing to see if the mean of the sample is only less than or only greater than
What is a Research Hypothesis: How to Write it, Types, and Examples
It seeks to explore and understand a particular aspect of the research subject. In contrast, a research hypothesis is a specific statement or prediction that suggests an expected relationship between variables. It is formulated based on existing knowledge or theories and guides the research design and data analysis. 7.
Types of Research Hypotheses
There are seven different types of research hypotheses. Simple Hypothesis. A simple hypothesis predicts the relationship between a single dependent variable and a single independent variable. Complex Hypothesis. A complex hypothesis predicts the relationship between two or more independent and dependent variables. Directional Hypothesis.
What is a Hypothesis
A directional hypothesis is a statement that predicts the direction of the relationship between variables. For example, a researcher might predict that increasing the amount of exercise will result in a decrease in body weight. ... Guides research: A hypothesis provides a clear and specific direction for research. It helps to focus the research ...
Developing the research hypothesis
The research hypothesis is needed for a sound and well-developed research study. The research hypothesis contributes to the solution of the research problem. Types of research hypotheses include inductive and deductive, directional and non-directional, and null and alternative hypotheses. Rejecting the null hypothesis and accepting the ...
Research Hypotheses: Directional vs. Non-Directional Hypotheses
A directional hypothesis predicts a specific direction of change, while a non-directional hypothesis predicts that there will be a difference between groups or conditions without specifying the direction of that difference. It's important to understand the difference between these types of hypotheses to conduct rigorous and insightful research ...
How to write a research hypothesis
A research hypothesis defines the theory or problem your research intends to test. It is the "educated guess" of what the final results of your research or experiment will be. ...
