Data from a study by the U.S. News and World Report magazine with the purpose of college ranking. Druzdzel and Glymour choose 8 variables and after removing some universities give a correlation matrix for 170 universities. The 8 variables are:
average percentage of graduation, i.e., the fraction of the total number of entering students who make it through the graduation,
rejection rate, i.e., the fraction of the applicants who are given an admission offer,
average standardized test scores of the incoming students,
class standing of the incoming freshman, which is a fraction of the incoming freshmen who were in top 10% of their high school graduating class,
percentage of those students who accept the university's offer from among those who are offered admission,
total educational and general expenses per student, which is the sum spent on the instruction, student services, and academic support, including libraries and computing services,
student-faculty ratio,
average facutly salary.
