To cnsure that if an experiment has male and female participants, all the males are in a. one group. To create roughly cquivalent groups at the beginning of the experiment. To provide a baseline for comparing the effects of other treatments. To allow participants to choose the groups the treatment they will reccive. b. C. 17.
