<p>FWIW I have data for over 100 schools, for circa 1970, on a spreadsheet.
I got out one of the old college guides when D1 was looking at colleges, because she said everything I “knew” was obsolete. So I went back and looked at the ordinal relative selectivity levels from when I was looking vs. when she was looking. Though much was similar there were indeed some changes.</p>
<p>The data that appeared in the guide books from that era were actually more complete than what I see now. They broke out colleges of multi-college universities separately, and also reported scores separately by gender.
that data was really interesting to see, the ranges for M and F were often quite different.</p>
