Can someone advise me on the following stats. I have a behavioural data set consisting of 7 variables one factor. I ran two MANOVAs on the data set addressing two different questions. I need to adjust the p values of the seven univariate tests within each MANOVA for the Bonferroni correction. However, some of the variables are correlated.
Two questions: How do I determine the appropriate adjustment for the Bonferroni correction on correlated variables, and because I ran a MANOVA on the same data twice, do I need to adjust the P value for each test according to the combined number of univariate tests, i.e. 2 sets of 7 tests = 14, or for each set of 7 univariate tests in turn.
Any advise will be most welcome.
