1

2
Q
In case of multiple dependent variables, why is it preferred to do a MANOVA in stead of multiple univariate ANOVA’s?
A
- several criterion measures will provide a more complete and detailed description of the phenomenon under investigation
- multiple univariate tests inflate overall type 1 error rate
- univariate analysis ignore important information: association between the dependent variables
- the use of a total score may not reveal significant effects due to a canceling out effect
