Does reading the Harry Potter books encourage tolerance? It depends. Italian fifth graders were (randomly) split into two groups. Half the students met with researchers and discussed passages from the Harry Potter books that handled prejudice, while the others talked about unrelated sections. *Data are fabricated but match actual results When determining whether or not the main effects and interactions were significant, for the sake of this assignment, let’s say that the difference between the calculated means/differences must be .7 or higher to be significant. Posttest attitudes toward immigration (7-pt scale) Discussed prejudice-related sections Discussed unrelated sections High identification w/ Harry 6.2 5.0 Low identification w/ Harry 4.2 4.4 Is there a main effect of identification? (calculate marginal means). Is there a main effect of section? (calculate marginal means). Is there an interaction effect? (calculate “difference of differences”)…
