Summarizing Categorical Data

A large business school conducted a study of graduation rate for their students. Out of 408 entering students in 1995, 55% had graduated within 6 years. Data for a random sample of 56 students are given below. `AGE' was their age upon entering the program, `HS GPA' was their cumulative high school GPA, `DORM'=1 means they lived in a dorm during their first year in college, `GPA2' was their college GPA after two years of college, and `GRAD6'=1 means they graduated within 6 years of starting college.

The variables MAJOR, SEX, DORM, and GRAD6 are categorical . The variables AGE, HS GPA, and GPA2 are numerical .
