Data set: Caucuses
The Caucuses data set contains the 2008 Democratic and Republican caucus results. Republicans count actual votes. Democrats don’t record individual votes, but each precinct allocates its delegates based on the number of people in the precinct supporting each candidate during the caucus. Senator Clinton was expected to win in most polls, but ended up a surprising third after Senators Obama and Edwards. Many political analysts have found that females, less educated people, and older people voted for Senator Clinton, while younger people, more educated people, and African Americans preferred Senator Obama.
a. Use the Caucuses data to test the hypothesis that education level is correlated to a higher percentage of votes for Senator Obama.
b. Use the Caucuses data to create a multivariate model that “best” predicts the percentage of delegates Senator Obama would win.
