 We interviewed 40 students and collected data to determine whether student’s age and gender would make a difference in their GPA.  The GPAs are higher for students working fewer hours during the week than for students working more hours during the week.  GPAs of college of business students are different from the GPA of students in other schools at the University Of Michigan-Dearborn.

 We interviewed 40 students from the campus.  55% of them were males and 45% females.  25% of them were below the age 21, 43% were between and the remaining were 23% above 25.  5% of surveyed were freshmen, 10% were Sophomore, 50% were junior and the remaining 35% were seniors.  30% of surveyed students worked 10 hours or less and the other 70% worked 10 hours or more.

 The average GPA was 3.23  The standard deviation was 0.32  The median was 3.25
