Using the "Business School Ranking" data set, Eli ran a regression model to identify factors that drive the change in salary (i.e., salary difference between post- and pre-program; in $). Specifically, he regressed the change in salary on Anlys (How good are the MBAs analytic skills?; 1 best to 6 worst), Team (How well do MBAs do within teams?; 1 best to 6 worst), Globe (How global is the education; 1 best to 6 worst), and Tuition (in $). Use Tables to answer to the question. Please NUMBER your answer; otherwise, your answer won't be graded. (1) What factors influence the change in salary? Provide a specific rationale behind your conclusion (2) Explain the relative importance of the regressors. Why can/can't you compare the relative importance? (3) Identify ONE potential issue with this regression model. Hint: Use the correlation table to uncover the issue (4) What does the R-Squared of .70 mean? Be specific as possible. (5) What does the Adjusted R-Squared of .62 mean? What is the key difference between R-Squared and Adjusted R-Squared?Table 1A.
