ANOVA vs. MANOVA
| ANOVA |
MANOVA |
| One dependent variable |
Multiple dependent variables |
| Univariate F value |
Multivariate F value (Wilks’ lambda) |
| Multiple independent variables (Multi-Factor ANOVA) is not MANOVA |
|
| based on a comparison of the Mean square error (Within-group variability) and the mean square effect (Between-group variability) |
based on a comparison of the error variance/covariance matrix and the effect variance/covariance matrix |
|
After getting a significant Multivariate effect, next step is to run Univariate test on each dependent variable to find which dependent variable was affected most and hence contributed in main multivariate effect. |
