Refer to the Journal of Applied 0 Psychology (June 2002) study of the effect of violence *O"EC and sex on a television viewer's ability to recall a TV commercial. Exercise 9.28 (p. 509). Recall that 324 adults were randomly assigned to one of three TV content groups, with 108 subjects in each group. One group watched a TV program with a violent content code (V) rating; the second group viewed a show with a sex content code (S) rating; and the last group watched a neutral TV program. Commercials were imbedded into each TV show, and after the participants viewed the show, the advertisement recall score was measured for each participant. In addition, the researchers recorded whether or not the subject had previously seen the commercial. The layout for the full experimental design is shown in the accompanying schematic. Note that there are two factors in this experiment-TV content group at three levels and watched commercial before status at two levels-and the design is a 3 × 2 factorial. The researchers want to know whether the two factors, TV content group and watched commercial before status, impact mean recall score. Conduct a two-way factorial analysis of variance on the data saved in the accompanying file. The researchers concluded that (1) the Neutral TV content group has the highest mean recall score, but that there is no significant difference between the mean recall scores of those who had previously watched the commercial and those who had not. Do you agree?
