I think you are mixing up what I am saying - or what that stat was saying. Firstly, if Walden University produced zero tenured professors it would end up weighting exactly the same in the data as random small private university that produced 10 PhDs that also didn't become professors. The state does not involve "eliteness". They simply ranked all schools by number of PhDs they produced and took the top 20%. And fwiw considering this would be about 90 universities Im almost certain every school you listed would make that cut. I guess all I'm saying is that it would be nice to know what percent of total PhDs the same 90 schools are accountable for. My guess is about 50%.
