Sure you can compare, @Chrchill - but it’s like comparing teams where one has many more draft picks than the others and being amazed by how many top-ranked players sign with that team. Or, if you’d prefer a golf analogy, it’s like claiming two players are equally as good because they shoot the same relative to their handicaps, but one has a handicap ten strokes higher than the other.
I have no ideological axe to grind here - I think UChicago is a top-tier university, and have often said so. They’ve also attracted many high-stats kids, helped by an unparalleled ability to cherrypick them from the ED pool and unimpeded by a “stats tax” they would have suffered if they had a bigger, D1 athletics program.
One has to have an ideological agenda, though, to claim with a straight face that two universities with yields in the low 70s have been demonstrated to be equally attractive when one takes over 80% of its class ED and the other takes less than 60% of its class EA.
