Chapter 7: Modeling Relationships of Multiple Variables ...

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 .

18 This type of logarithmic relationship can still be tested using linear regression techniques, but it requires transforming data so that the model corresponds to the way the data are actually configured. Describing these transformations is beyond the scope of this book, but for a description of these methods, see Applied Linear
