Hello,
I performed a two factor ANOVA; one factor (sex) has 2 levels and the other factor (race) has 3 levels. The interaction term is not significant but one of the factors, race, is (p=0.0004). How can I determine which means are different while maintaining the experiment wise type I error rate.
If I had only one factor, I could use -oneway- and then use, for example, scheffe for multiple comparisons. But not sure what to do with two factors.
Thank you in advance,
Ricardo
