Predict success in graduate school with regression.
Go to Canvas and download SuccessInGradSchool.pdf. ETS (Educational Testing Service) Owns the GRE (Graduate Record Exam). In 2005 they performed a large study to predict success in graduate school. They used a multiple regression model with three factors Undergraduate Grade Point Average (U), GRE Verbal score (V), GRE Quantitative score. Note that they have a vested interest in proving the GRE scores have merit. The investigators are professionals from an elite institution with a sizable research budget.
Go to page 23 in their report “Table 3 Predicting Cumulative Graduate Grade Point Average.” They report the multiple R score for each of five different majors. Furthermore, they believe that the multiple R scores are underestimates, so they show “corrected multiple R” scores. Examine these key findings, and comment on the success of their multiple regression equations. Explain your reasoning.
