assuming you mean waitlisted after being interviewed, calculated from stats graciously provided by brettp11 here:
ALL Applied Interviewed Accepted Enrolled STATS
i make a couple of assumptions in calculating these data. you can interpret them any way you like.
1) i've heard that some schools initially send out 2x # acceptances as they have seats, so this i assume
this is an extreme assumption. i don't believe any schools initially send out more than 2x but many send out less. the less acceptances they send out initially, the better chance for you if you're on the waitlist.
2) i assume everyone interviewed was either accepted or waitlisted. since this is obviously not true and some schools reject post-interview, then being on the waitlist post-interview would mean a greater likelihood of eventually being accepted.
how i calculate:
I. (#accepted - 2*#enrolled) = # accepted off waitlist
II. (#interviewed - 2*#enrolled) = # waitlisted
III. (# accepted off waitlist / # waitlisted) = % taken off waitlist
feel free to edit/correct. i am doing this coming off a demerol/codeine buzz
Vanderbilt
applied interviewed accepted enrolled
Total: 3,427 835 302 104
I. 302 - 2*104 = 98
II. 835 - 302 = 533
III. 98/533 *100% =
18.4%
UCSD
Total: 4,255 522 312 121
I. 312 - 121*2 = 79
II. 522 - 312 = 210
III. 79/210 * 100% =
37.6%
UCLA
Total: 5,308 613 240 121
(hmmmm. we'll get a negative here. not too many people decline ucla, it seems)
I. 240 - 121*2 = -2
II. 613 - 240 = 373
III. -2/373 * 100%
< 0.
but i know people who've been accepted off the waitlist, so ucla probably doesn't initially send out acceptances for 2x the number of seats available.
other calcs assuming sent out acceptances for 1.5x number seats initally
I. 240 - 121*1.5 = 58
II. 613 - 240 = 373
III. 58/373 * 100% =
15.5%
Stanford
Total: 5,813 560 186 86
I. 186 - 86*2 = 14
II. 560 - 186 = 374
III. 14/374 =
3.7%
