Multiple regression is a set of techniques for generating a predicted score for one variable from two or more predictor variables. And the nice thing about multiple regression is that it’s just an extension of regression with one predictor variable. All of the basic principles we covered in the last chapter still hold true in this chapter.

An especially useful application of multiple regression analysis is to determine whether a set of variables (Set B) contributes to the prediction of Y beyond the contribution of a prior set (Set A). The statistic of interest here, R squared added, is the difference between the R squared for both sets of variables (R2Y.AB) and the R squared for ...

There is sufficient sample size. It is recommended that there be at least 10 to 20 cases (observations) for each variable in the analysis (Cohen & Cohen, 1983). Multiple regression is based on multiple correlation. As noted above, several variables may be used as predictor variables.
