Quizplus · Accepted Answer

This design is a randomized subjects, posttest only control group design because two groups are randomly assigned and a test is administered after the intervention (or lack of intervention) has occurred. There is no manipulation of variables like in a factorial design or a counterbalanced design, and there is no pretest or static group control.
