This chapter shows how to enter data and prepare SAS programs that will perform a one-way multivariate analysis of variance (MANOVA) using the GLM procedure. You can think of MANOVA as an extension of ANOVA in that it allows for the inclusion of multiple criterion variables in a single computation. This chapter focuses on the between-subjects design in which each participant is assigned to only one condition under the independent variable. You are shown how to summarize both significant and nonsignificant MANOVA results.
