Should "typical" college freshmen plan on 9+ semesters?

<p>This is an absurd question. Anyone can find out that the <em>six-year graduation rate</em> is 55% at public universities. It seems reasonable to conclude that the “typical” struggles to graduate within six years, much less 9 semesters.</p>

<p>As for not making conclusions from “raw” statistics, I thought one of the ideals of statistics was a representative population. If you don’t have “raw” statistics, what statistical conclusions can you make?</p>
