I want to perform a MANOVA in SPSS as follows: i have a independent variable that consists of three groups (- of which the group sizes are not equal), and six dependent variables. When checking the Levenes test for equality of error variances To test this assumption, use Levenes homogeneity-of-variance test, available in the One-Way ANOVA procedure.For the difference in means: mean, standard error, and condence interval (you can specify the condence level). Tests: Levenes test for equality of variances and both The SAS TTEST procedure and SPSS T-TEST command conduct F tests for equal variance.
