A scatterplot with regression line is shown below for a regression model using Verbal SAT score, VerbalSAT, to predict grade point 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 + 0.00189VerbalSAT.
