Answer to Question 1

With a posttest-only control group design we do not have to worry as much about demand characteristics, experimenter effects, or practice or fatigue effects. However, because we do not use a pretest, we cannot be absolutely sure that the participants are equivalent at the beginning of the study. With the pretest/posttest control group design, we can be sure of equivalency of subjects, however we need to be more concerned about demand characteristics, experimenter effects, and practice and fatigue effects.

Answer to Question 2

True
