Document Summary
Difference between all the groups and any pairwise differences. Looking for main effects and also interactions between ivs. F for me #1, me #2, interaction (3) Bonferroni or tukey"s -> direction, sig of differences. As needed, tukey -> direction, sig of differences. True experimental because both ivs can be manipulated. Marginal means is how you get the main effect. Yes there is a main effect for race: same = 40, different = 30. Participants recalled significantly more details when the crime depicted a perpetrator of the same race than participants who viewd a crime that depicted a perpetrator of a different race. Yes me for type of crime: nonviolent mean = 45, violent = 25. Participants recalled significantly more details when presented with a crime that was nonviolent then participants who viewed a crime that was violent. No interaction (see figure): the effect of race on recall does not depend on type of crime.
