To determine if dancing enhances mood, you recruit 100 voluntary participants. You randomly select 50 and give them seven free dance lessons; the other 50 get no dance lessons. After the seventh class, you administer the Acme Happiness Scale Survey (AHSS) to all 100 individuals; this survey renders a score ranging from 1 to 30 (1 = Extremely unhappy . . . 30 = Extremely happy).
