3. You are DONE with the political candidate. They were simply working you too hard. You have taken a new job working as a research assistant for a social science researcher. The researcher is working on a project focusing on the racial attitudes of whites in the PS, and is particularly interested in how region affects such attitudes. You are assigned to this project and so you turn to the literature and find that whites who live in the southern part of the uS. tend to have more negative racial attitudes than do people who live outside of the south. Given the history of the u._S. you do not find this to be too surprising but you want to explain why this disparity exists. You read more and discover that whites in the tend to less well educated than are whites who live outside of the 5914th, and that education is positively associated with liberal, or positive, racial attitudes (i.e., the more education one completes the more likely they are to have positive racial attitudes). So you go back to the GSS and recode the variable 'region! into two categories: 1= lives in south and O = lives outside of the You also compute an index of racial attitudes that ranges from O (which reflects the most negative racial attitudes) to 4 (which reflects the most positive racial attitudes). You have SPSS estimate some nested regression models and you get the following results: Results of OLS regression models predicting racial attitudes amon whites, GSS2016 Predictor South (vs. not South) Years of education Constant adj.
