1. To use the techniques in this chapter for factorial ANOVA and have confidence about the p values, the data must meet six requirements. List them.
2. Two social psychologists asked freshman and senior college students to write an essay supporting recent police action on campus. (The students were known to be against the police action.) The students were given $20, $10, $5, or $1 for their essay. Later, each student's attitude toward the police was measured on a scale of 1 to 20.
Perform an ANOVA, fill out a summary table, and write an interpretation of the analysis at this point. (See Brehm and Cohen, 1962, for a similar study of Yale students.) If appropriate, calculate HSDs for all pairwise comparisons.Write an overall interpretation of the results of the study.
