Quizplus · Accepted Answer

In the posttest only control group design, participants are randomly assigned to either an experimental group or a control group, but only measured on the dependent variable after the experimental treatment or intervention has been applied. This design does not include a pretest, making option C incorrect, and it does involve both control and experimental groups, making option E incorrect. It is not a pre-experimental design (A) because it includes random assignment, and the independent variable is manipulated before the measurement, not after, making D incorrect.
