Chapter 7:
Modeling Relationships of Multiple Variables with
Linear Regression
Overview Chapters 5 and 6 examined methods to test relationships between two variables. Many research projects, however, require analyses to test the relationships of multiple independent variables with a dependent variable. This chapter describes why researchers use modeling and then examines one of the most powerful modeling approaches linear regression. We show how to interpret regression statistics and graph linear regressions using the STATES data. Finally, we discuss issues related to data structures and model building.
