For a follow-up on Demonstration 11.1, pick two variables that measure social class. If necessary, recode these variables so that they have only two or three categories. Run the Crosstabs procedure with spanking as the row variable and your new measures of social class as the column variables. How do these relationships compare with the table generated in Demonstration 11.1? Are these tables consistent with the idea that approval of spanking is dependent on social class?
