Detailed explanation-1: -When using this kind of design, researchers try to account for any confounding variables by controlling for them in their analysis or by choosing groups that are as similar as possible. This is the most common type of quasi-experimental design.
Detailed explanation-2: -What Is a Quasi-experiment? Quasi-experiments are studies that aim to evaluate interventions but that do not use randomization. Similar to randomized trials, quasi-experiments aim to demonstrate causality between an intervention and an outcome.
Detailed explanation-3: -In a quasi-experimental design, the researcher changes or watches an independent variable, but the participants are not put into groups at random.
Detailed explanation-4: -Quasi-experiments are commonly used in social sciences, public health, education, and policy analysis, especially when it is not practical or reasonable to randomize study participants to the treatment condition.
