Question

Quizplus · Accepted Answer

Pretesting for scores on the dependent variable examines group equivalence and can assess mortality effects, which can help ensure the validity of the experimental results. However, pretesting can also limit the generalizability of the results if the pretest itself affects the participants' responses to the independent variable. Therefore, the best choice is D because it acknowledges both the benefits and potential limitations of pretesting.
