I really like the concept. However, what are you using for "XLSAT" and "XGPA"? Looking at your Emory example, I couldn't really tell.
Also, I think of W&L as being a school that emphasizes LSAT over GPA, but didn't see it on here.
Also, do you have a link to the Admission Index Information Sheet that's backing this up? I couldn't find it on LSAC and would really like to see it - although I'm not a hard-core math geek, I have a soft spot for statistics
Thanks for the feedback. Here's the original data source:
I'll update my page with it. It may be that W&L doesn't use the "Index" system. (?) I'll add some text to make it clear that not all schools do this.
You're right - W&L doesn't use an index. Here's an interesting LSAC search result (although it lacks the broader applicability of your system) on entering student statistics (done from this page: http://officialguide.lsac.org/search/cgi-bin/KeyFact.asp?Group=2
75%-LSAT > 165
2.75 < 25%-GPA < 3.25
Cardozo School of Law 166 3.19
George Mason University School of Law 166 3.15
University of Illinois College of Law 167 3.04
Washington University School of Law (St. Louis) 167 3.2
Washington & Lee 166 3.25
OK - I had to add the last one in manually, since W&L's 25%ile GPA is 3.25 exactly.
At the other end of the spectrum, the following search emphasized low LSAT, high GPA schools:
25%-LSAT < 155
75%-GPA > 3.7
25%-GPA > 3.2
