A quasi-experiment is a research design used to estimate the causal impact of an intervention. Quasi-experiments share similarities with experiments and randomized controlled trials, but specifically lack random assignment to treatment or control. Instead, quasi-experimental designs typically compare groups that are either preexisting (e.g., different dog breeds) or groups that were created without random assignment (e.g., students attending different universities).
