It is suggested that a block design, blocking by gender, be used. Why is a block design preferable to a completely randomized design for this experiment? We should usc a block design because it creates groups that are foughly the cquivalent at the beginning of the experiment. We should use a block design because we must keep all other variables the same except for the type of gender for the volunteers to prevent confounding. We should use a block design because it provides a baseline for comparing the differences in the dandruff between males and females. d. a. b. с.

If the results show that the new medication is significantly more effective than the old medication, we can conclude that the new medication will be more effective for all people that have a moderate case of the disease.
