Like a true experiment, a quasi-experimental design aims to establish a cause-and-effect relationship between an independent and dependent variable. However, unlike a true experiment, a quasi-experiment does not rely on random assignment. Instead, subjects are assigned to groups based on non-random criteria.

Similar to randomized trials, quasi-experiments aim todemonstratecausalitybetweenaninterventionandanoutcome. Quasi-experimental studies can use both preintervention and postintervention measurements as well as nonrandomly selected control groups.
Quasi Experimental Design Overview & Examples - Statistics by Jim
What is a Quasi Experimental Design? A quasi experimental design is a method for identifying causal relationships that does not randomly assign participants to the experimental groups. Instead, researchers use a non-random process. For example, they might use an eligibility cutoff score or preexisting groups to determine who receives the treatment.
Quasi-experimental Research: What It Is, Types & Examples
Quasi-experimental research compares groups with different circumstances or treatments to find cause-and-effectlinks. It draws statistical conclusions from quantitative data. Qualitative data can enhance quasi-experimental research by revealing participants’ experiences and opinions, but quantitative data is the method’s foundation.
Quasi-Experimental Research Design - Types, Methods
The key purpose of quasi-experimental design is toevaluatethe impact of an intervention, policy, or program on a targeted outcome while controlling for potential confounding factors that may affect the outcome.

Explain what quasi-experimentalresearchis and distinguish it clearly from both experimental and correlational research. Describe three different types of quasi-experimental researchdesigns (nonequivalent groups, pretest-posttest, and interrupted time series) and identify examples of each one.

LEARNING OBJECTIVES. Explain what quasi-experimentalresearch is and distinguish it clearly from both experimental and correlational research. Describe three different types of quasi-experimentalresearch designs (nonequivalent groups, pretest-posttest, and interrupted time series) and identify examples of each one.
The primary purpose of quasi-experimental design is to investigate cause-and-effect relationships between variables in real-world settings. Researchers use this approachtoanswerresearchquestions, test hypotheses, and explore the impact of interventions or treatments when they cannot employ traditional experimental methods.
Quasi-experiment - Wikipedia
A quasi-experiment is an empirical interventional study used to estimate the causal impact of an intervention on target population without random assignment.

Specifically, we describe four quasi-experimentaldesigns – one-group pretest–posttest designs, non-equivalent group designs, regression discontinuity designs, and interrupted time-series designs – and their statistical analyses in detail.
