Stats for rejected students?

So I know there are a lot of places you can find the stats of the average admitted student at X or Y university, but is there some sort of similar data available for the rejected students? For example, if I wanted to know the average SAT score of someone rejected from X University, is there somewhere I could look to find that? Thank you.

Someone else may have the answer to this for the entire applicant pool, but we found Naviance useful for assessing the stats of accepted, wait listed, and rejected students from my son’s HS for the colleges he was considering.

You should also check out Parchment, as applicants can enter their stats and which schools they were admitted/waitlisted/rejected to, and you can view each profile.
