Here is a reference for you. It only really makes sense to do the
multivariate analysis if the composites that are analyzed really make
sense.

Subject: Re: MANOVA vs. Repeated Measures ANOVA

Dear List,

I have 5 DV (i.e., student GPA, number of disciplinary referrals, days a
student was absent from school, etc.). These DVs were measures twice
(the beginning of the semester and at the end). My IV is level of
participation in program activiteis.  I used Repeated Measures ANOVA.
The reviewers of the manuscript made the following comment:

Why MANOVAs (vs ANOVA) were not conducted to account for the
correlations (relatedness) between dependent variables?

Can anybody help and explain when it is more appropriate to use MANOVA
vs ANOVA?

Thank you in advance,

Lana
