ABSTRACT

In this chapter you will:

Be introduced to multiple regression and learn how to interpret the basic multiple-regression statistics.

Learn how to estimate R 2 for a population from the R 2 computed for a particular sample.

Learn how to determine the amount of variance two predictor variables account for together and whether that amount is statistically significant.

Learn how to determine the amount of additional variance a second predictor variable accounts for, above and beyond the portion of variance accounted for by the first, and whether that additional amount is statistically significant.

Be introduced in a basic way to concepts underlying the analysis of covariance.

Learn how to generalize the techniques discussed in this chapter from two to more than two predictor variables.
