> It provides mean nationwide SAT score numbers, and the provided comparison assumes that nationwide scores are reflective of Ivy applicant scores.
Does it really assume that? Suppose, for the sake of argument, one group had a nationwide average SAT score of 1500, and all other groups had an average SAT of just 500. Barring any bizarre distributions of those scores, we can infer from only the averages, that the 1500-SAT group would have more individuals that satisfy a university's academic criteria, than the 500-SAT groups. It's far from perfect, but does provide a hint.
> Also, the overall analysis assumes that per capita distribution is fair but that seems subjective.
I must have missed where in those charts a definition of 'fair' is given, and then relied on for further analysis.
> of course there is no mention of Hispanic students
Hispanic students are between Asian and Black on every chart.
> And then it doesn't get into international students
That is correct, international students are entirely excluded, in the sense that all the domestic students in a school are taken to represent 100%. I don't understand how not answering all these additional questions you raise makes the data irrelevant.
