B. In your opinion, would it be informative to include a control group in a study such as this one? Explain. (t-Test for Dependent Groups with Effect Size I, pp. 140-142)
C. Is it worth research dollars, researcher time, and participant time to run a study with 50% power? Explain. (Statistical Power, pp. 150-153)
D. Suppose there had been no interaction. Briefly describe how Figure 1 would have been different. (Two-Way ANOVA I, pp. 162-164)
