Quantitative Methods Questions
A quasi-experimental design is a research design that resembles an experimental design but lacks random assignment of participants to treatment groups. In a quasi-experimental design, researchers still manipulate an independent variable and measure its effects on a dependent variable, but they do not have full control over the assignment of participants to groups. Instead, participants are assigned to groups based on pre-existing characteristics or natural occurrences. This design is often used when random assignment is not feasible or ethical, such as in studying the effects of certain policies or interventions on a specific population.
