Examine attitudes toward affirmative action based on two variables: AFFRMACT and DISCAFF. AFFRMACT measures respondents' support of preferential hiring and promotion of blacks (a higher score indicates opposition). For the variable DISCAFF, individuals reported how likely it is that a white person won't get a job or promotion while an equally or less qualified black person gets one (a higher score indicates "not very likely"). Using AFFRMACT and DISCAFF as your dependent variables, determine whether there are significant differences in attitudes by social class (CLASS)? (You should have two ANOVA models, with CLASS as the independent variable in both models.)
