ABSTRACT
In Chapter 8, the concept of correlation was introduced. Correlation involves a meas ure of the degree to which two variables are related to each other. A closely related concept, coefficient of determination, was also introduced in that chapter. This statistic provides a meas ure of the strength of the association between two variables in terms of percentage of variance explained. Both of these concepts are present in regression. In this chapter, the concepts of simple linear regression and multiple regression are introduced.
