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 STATES10 data. Finally, we discuss issues related to data structures and model building. The Advantages of Modeling Relationships in Multiple regression In most studies, building Multiple regression models is the final stage of data analysis. These models can contain many Variables that operate independently, or in concert with one another, to explain variation in the dependent variable .
Chapter 7 • Modeling Relationships of Multiple Variables with Linear Regression 163 more sophisticated understanding of social behavior, and more informed policy recommendations. Finally, one of the great advantages of mulitple regression models is that they allow for the inclusion of control variables. Control variables not only help ...
