Discussion questions for group comparisons and interaction effects If time permits we will go over these in class or lab; otherwise just think about them on your own. 1. The notes present several models for interaction effects. a. Suppose your dependent variable is LIBERALISM (measured on a scale that runs from 400 to 1200). Your independent variables are FEMALE (1 = Female, 0 = Male), PARENT’S LIBERALISM (same 400 to 1200 point scale), and INCOME (measured in thousands of dollars). Using interaction effects, what would be a reasonable sequence of models where you gradually went from totally constrained (no differences between men and women) to totally unconstrained (All effects differ for men and women)? In brief, what would each of these models be saying about the extent and nature of differences between men and women? b. The notes make a distinction between compositional differences versus differences in variable effects. In the present example, what would be evidence of each? Explain why and how, even if
