You don't go by number of sports only but of total scholarships awarded in proportion to the student population, at least that is my understanding of it and i just did a little research to confirm it. (http://www.sadker.org/TitleIX.html)
Football really skews everything since there are no women's sports that provide anywhere close to the number of scholarships that football does. Thus, to keep the scholarship numbers equitable, you will almost always see more women's scholarship sports than men's scholarship sports at most colleges.
