Examine these key findings, and comment on the success of their multiple regression equations. Explain your reasoning.

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.
