<p>The last official data I could find was from [1997-2002[/url</a>], in which the mean GPA was 3.36 (note that median may be lower, since the grade distribution is most likely skewed by outliers at the top). An unscientific Daily Princetonian poll found [url=<a href=“http://www.dailyprincetonian.com/archives/2006/10/11/news/16142.shtml]a”>http://www.dailyprincetonian.com/archives/2006/10/11/news/16142.shtml]a</a> median between 3.2 and 3.3 and a mean of 3.52](<a href=“http://www.princeton.edu/odoc/faculty/grading/grading_proposals/04.html]1997-2002[/url”>http://www.princeton.edu/odoc/faculty/grading/grading_proposals/04.html) for the class of 2006.</p>
<p>Thus it seems fair to say that the median GPA is probably in the range of 3.1 - 3.3 (since the Princetonian poll likely overshot the actual numbers slightly) and the mean somewhat higher than that – around 3.4, probably.</p>
<p>Interestingly enough, Princeton informs students of their [quintile</a> GPA rankings](<a href=“http://www.dailyprincetonian.com/archives/2004/09/22/news/10792.shtml]quintile”>http://www.dailyprincetonian.com/archives/2004/09/22/news/10792.shtml). If a bunch of current students posted their GPAs and corresponding quintile ranking, a very accurate distribution could be constructed.</p>
