1. How do I interpret the Box's Test of Equality of Covariance Matrices SPSS output?

An assumption of the MANOVA is that the covariance matrices of the dependent variables are the same across groups (i.e., levels of the independent variable) in the population. Box's M tests that assumption. In this case, the p value of .000 suggests that the hypothesis of equal covariance matrices is rejected. So we have violated the homogeneity of covariance assumption of MANOVA. It is ...
