MULTIPLE REGRESSION measures the effect a group of survey questions (called the independent variables) has on a single survey question (or an average of a group of questions), called the dependent variable.
In a multiple regression, multiple R can be viewed as the correlation between the actual and predicted values of the dependent variable. It can only be between zero and one (since it uses a sum of squares in its calculation, and these cannot be negative).
