A psychologist studying artistic preference randomly assigns a group of 45 participants to one of three conditions in which they view a series of unfamiliar abstract paintings. The 15 participants in the Famous condition are led to believe that these are each famous paintings; their mean rating for liking the paintings is 6.5 (S = 3.5). The 15 in the Critically Acclaimed condition are led to believe that these are paintings that are not famous but are very highly thought of by a group of professional art critics; their mean rating is 8.5 (S = 4.2). The 15 in the Control condition are given no special information about the paintings; their mean rating is 3.1 (S = 2.9). Does what people are told about paintings make a difference in how well they are liked? Use the .05 level. Famous: S2 = 12.25 Critically acclaimed: S2 = 17.64 Control: S2 = 8.41
