<p>“Duke’s yield is higher than that of UChicago, Northwestern, Cal Tech, Johns Hopkins, Vanderbilt, and Wash U among others. Yield is an easily manipulated statistic and 45% is not surprisingly low.”</p>
<p>Northwestern, JHU, Vanderbilt, Wash U, yes. But these are schools that Duke should be beating by a large margin anyway. Caltech and Chicago are on EA, and if they moved to ED, they would almost certainly have a higher yield than Duke.</p>
<p>Regardless, Duke’s yield isn’t terribly low and is consistent with its level of prestige. Its yield is slightly lower than Dartmouth’s, a school on the same level of prestige.</p>
