<p>Ah, the Holy Grail of “outside” statisticians! Outside as in looking at the numbers like you and I have to do! This issue comes up when trying to dissect the Ivy League (as an example) and speculating about how many of the 200,000+ applications are unique. The multiple applications have led some to claim that the admissions percentages are way above the 10 percent shown by raw numbers. True as it is, we also have to see that each school receives unduplicated applications. </p>
<p>Again, the UC statistics lift a bit of the veil, but this issue remains cloudy.</p>
