As part of a study at a large university, data were collected on n = 224 freshmen computer science (CS) majors in a particular year. The researchers were interested in modeling y, a student’s grade point average (GPA) after three semesters, as a function of the following independent variables (recorded at the time the students enrolled in the university): = average high school grade in mathematics (HSM) = average high school grade in science (HSS) = average high school grade in English (HSE) = SAT mathematics score (SATM) = SAT verbal score (SATV) A first-order model was fit to data with R2 = 0.211.
