Quizplus · Accepted Answer

True experiments involve random assignment of participants to different experimental conditions. This creates equivalent groups, allowing for a comparison of the effects of the independent variable on the dependent variable. Quasi-experiments, on the other hand, do not involve random assignment, and thus lack the same level of control over extraneous variables. While correlational methods may be used in both types of studies, random selection and random assignment are unique to true experiments.
