The director of college admissions at a local university is trying to determine whether a student’s high school GPA or SAT score is a better predictor of the student’s subsequent college GPA. She formulates two models:
Model 1. College GPA = β0 + β1High School GPA + ε Model 2. College GPA = β0 + β1SAT Score + ε
She estimates these models and obtains the following goodness-of-fit measures.
Model 1 Model 2 R2 0.5595 0.5322 Adjusted R2 0.5573 0.5298 Se 40.3684 41.6007
Which model provides a better fit for y? A. Model 1 since it has a smaller standard error of the estimate and a higher coefficient of determination. B. Model 1 since it has a higher standard error of the estimate and a smaller coefficient of determination. C. Model 2 since it has a smaller standard error of the estimate and a higher coefficient of determination. D. Model 2 since it has a higher standard error of the estimate and a smaller coefficient of determination.
