Question

Quizplus · Accepted Answer

Quasi-experimental designs have moderate control because researchers are not able to randomly assign participants to conditions. This lack of randomization means that participants may differ in systematic ways before the study even begins, making it difficult to attribute any observed differences between groups to the experimental manipulation alone. However, researchers can still exert some control over the study by carefully selecting and matching participants, and using statistical techniques to account for any pre-existing differences.
