Using Clustering to Develop a College Football Ranking System

The College Sports Council tracked male and female varsity athletic participation by gender among NCAA member schools from 1980 to 2005. Their figures show an increase in female athletes per member school from 100 to 120 between 1980 and 1985, a flattening of participation rates from 1985 to 1994, and an increase from 115 to 160 from 1994 to 2005. ................
