MANOVA

Type classification: this is a notes resource.

Use multivariate analysis of variance (MANOVA) when multiple DVs are correlated with one another, but not overly so.

If there is little correlation between DVs, use multiple univariate ANOVAs instead.

Unequal cell sizes and missing data are problematic for MANOVA.

Low power can mean a non-significant multivariate effect but one or more significant univariate Fs.

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 may be:
   1. Main effects between multiple DVs
   2. Main effects between the multiple occasions
   3. Main effects of IVs
   4. Interactions between IVs and the DVs.
