Quizplus · Accepted Answer

ANCOVA is the most appropriate statistical procedure with a pretest/posttest design because it can control for the effect of the pretest scores on the posttest scores. This allows for a more accurate assessment of the differences between the groups on the posttest scores. MANOVA, independent t-test, and four-way ANOVA are not appropriate because they do not account for the effects of the pretest scores.
