Quasi-experimental design is a type of research methodology that seeks to evaluate the effect of an intervention or treatment without the use of random assignment to groups. This approach is often utilized when randomization is impractical or unethical, allowing researchers to assess causal relationships while acknowledging potential confounding variables. Quasi-experimental designs typically involve comparison groups that may not be equivalent at baseline, thus offering insights into the effectiveness of interventions in real-world settings.
