<p>Although you are correct that if you average all scores Penn is above Harvard, Yale, Princeton, this is a very strange thing to do. Penn had more programs ranked.
It really would be more appropriate to compare averages of nonzero scores.
In this type of a ranking a zero score indicates that the university was not ranked in that area.
If you look at the average of non zero scores it does give you an idea of which schools are really strong as research institutions. Penn at 14 seems about right and I should say that 14 is actually very good. Note for example where Duke, Johns Hopkins and Carnegie Mellon are , all very strong institutions.</p>
