A university official at a midwestern college compiled data on a random sample of students that might be used to build a model to predict their first year GPA. For each student, the following information was recorded: GPA : first year college GPA (out of 4.0) HSGPA : high school GPA (out of 4.0) SATV : score on the verbal/critical reading component of the SAT SATM : score on the math component of the SAT HU : number of credit hours from humanities courses in high school SS : number of credit hours from social science courses in high school Sex : sex of student (Male or Female) FirstGen : first generation college student (Yes or No) The first three rows of the data set are shown below.
