ABSTRACT
This chapter begins with a discussion and example of simple, or bivariate, regression. It reviews several other related concepts, and introduces several issues. The chapter discusses regression to other approaches with which students may be more familiar, such as analysis of variance (ANOVA). It demonstrates that ANOVA and regression are fundamentally the same process and that, in fact, regression subsumes ANOVA. Students have good data analytic habits: they check basic descriptive data prior to doing the main regression analysis. The regression equation may be used to graph the relation between Math Homework and Achievement, and this graph can also illustrate nicely the predictions. There are a few more details to study for the regression analysis before stepping back and further considering the meaning of the results. The standardized regression coefficient is the same as the correlation coefficient.
