Multivariate analysis of variance

Resource type: this resource consists of notes.

1. The best choice is a set of DV’s uncorrelated with one another because they each measure a separate aspect of the influence of IV’s.
2. When there is little correlation among DV’s univariate F is acceptable.
3. Unequal cell sizes and missing data are problematical for MANOVA.
4. Low power can mean a non-significant multivariate effect but one or more significant Univariate F’s!

Repeated-measures MANOVA

Extension of MANOVA, e.g., involving:

1. Multiple DVs (e.g., Social, Campus, and Teaching/Education Satisfaction)
2. Multiple Occasions (e.g., 1st, 2nd, 3rd year)
3. Any number of IVs (e.g., Gender)
4. Of interest are:
   1. Main effects of the multiple DVs
   2. Main effect of the multiple occasions
   3. Main effects of IVs
   4. Interactions b/w IVs and the DVs.
