Each year U.S. News & World Report conducts its "Survey of America's Best Graduate and Professional Schools." The top 25 business schools in 1991, as determined by reputation, student selectivity, placement success, and graduation rate, are listed in the table. For each school, three variables were measured: (1) GMAT score for the typical incoming student; (2) student acceptance rate (percentage accepted of all students who applied); and (3) starting salary of the typical graduating student. School GMAT Acc. Rate (%)...
