As a multivariate procedure, it is used when there are two or more dependent variables, and is typically followed by significance tests involving individual dependent variables separately. It helps to answer: 1. Do changes in the independent variable(s) have significant effects on the dependent variables? 2. What are the relationships among the dependent variables? 3. What are the relationships among the independent variables?"
