Regression Model
A multiple regression model was developed to predict the grade point average (GPA)for MBA students based on two entrance exam scores,verbal (VGMAT)and math (MGMAT).The following table shows the actual GPA and predicted GPA for 7 students.
$$\begin{array} { | c | c | c | } \hline \text { Student } & \text { Actural CPA } & \text { Predicted CPA } \\\hline 1 & 3.5 & 3.71 \\\hline 2 & 3.1 & 3.19 \\\hline 3 & 3.2 & 3.10 \\\hline 4 & 4.0 & 3.74 \\\hline 5 & 3.6 & 3.52 \\\hline 6 & 3.2 & 3.27 \\\hline 7 & 3.7 & 3.78 \\\hline\end{array}$$
