<p>I believe the data are restricted to students who received some form of Title IV federal aid. That might make a difference.</p>
<p>It took about a half hour. I downloaded a data set from IPEDS, imported into a spreadsheet, did calculations using formulas. I have similar data for another 260 schools.</p>
<p>Here is the description of this data from the IPEDS site for PRIVATE schools. There is a similar description for PUBLIC school data.
