ABSTRACT
This chapter focuses on which research questions lead us to looking at interaction effects and shows how interaction and elaborated crosstabs are related. It discusses interaction effects between a dichotomy and a ratio-level variable and examines interaction effects between two dichotomies. The chapter also provides interaction effects involving reference groups and presents interaction effects between two ratio-level variables. It argues how researchers used interactions to study the effects of a school arts program and how researchers used interactions to study work-related guilt. It is possible to examine relationships akin to regression interaction effects by using elaborated crosstabulations. The chapter looks at the example of sex, income, and health. It is known that income affects health, but now the chapter elaborates this relationship to see if, among various subgroups, the relationship is stronger, is weaker, or even remains at all. It presents two crosstabulations of income and health: one for men and one for women.
