Verbal SAT as a Predictor of GPA A scatterplot with regression line is shown below for a regression model using Verbal SAT score, VerbalSAT, to predict grade poin average in college, GPA, using the data in StudentSurvey. We also show computer output of the regression analysis below. The regression equation is GPA = 2.03 +0.00189 VerbalSAT.
