For University of Kentucky, fall 2002 formal rush:
1.How many girls start formal rush. -- 899
2. How many are left when prefs come around or the invitational rounds that determine quota. -- 730 attending pref
3. What was Quota. -- 62
4. How many of the final girls from prefs were placed. -- 668 received bids (689 signed pref cards).
5. How many sororities? 13 Panhellenic sororities participating in formal rush.
6. How many groups made/missed quota and by what amount if you remember? I *think* something like 9 sororities made quota, but I can't remember.
All of this info came from
http://www.uky.edu/StudentAffairs/Greek/FORMAL02.htm, which includes many more statistics like number dropping after each round, percent receiving their first choice for bids, etc. Apparently UK's Panhel doesn't care to keep this stuff secret.
If anyone has any idea how quota is calculated, maybe you could look at something -- I've always heard rumors about how Panhel here always screws up quota and total, that it shouldn't be what it is, but I've never been able to figure it out.
