Vanderbilt University
Washington University in St Louis
Yale University</p>
<p>Distance from home is a factor in college decisions but is controlled if you compare home state with home
state on a one-to-one basis.</p>
<p>For example:
Stanford attracts students from Massachusetts and Harvard attracts students from California. Which has
stronger drawing power in their competitor’s home state? </p>
<p>I have calculated a sort of “index of attraction” between each university and their competitor’s home states. </p>
<p>It indicates who wins in the head-to-head competition for students in each other’s states. It is a measure of
“animal magnetism”.</p>
<p>The index is calulated using the:
(1) number of enrolled freshmen 2006 from the competitor’s state
(2) total number of freshmen 2006 from that state who attended any private research university in the US
-included about 60 private universities
(3) number of freshmen in the freshman class</p>
<p>The basic idea is to take the number of students from the competitor’s state and adjust it for (a) the size of
the freshman class and (b) the total number of students from the competitor’s state who sought enrollment
at a private research university. I’ve tried my best to control for confounding factors and to standardize the
index.</p>
<p>For example:
Stanford attracts students from Massachusetts. Harvard attracts students from California. Which has
stronger drawing power in their competitor’s home state? </p>
<p>The Stanford freshman class (n=1646) had 22 students from MA. Massachusetts sent a total of 6,145
freshmen to private research universities.</p>
<p>The Harvard freshman class (n=1686) had 258 students from CA. California sent a total of 7,952 freshmen to
private research universities. </p>
<p>Stanford’s MA “magnetism” index = (22/1646/6145)<em>1000000 = 2.2.
Harvard’s CA “magnetism” index = (258/1686/7952)</em>1000000 = 19.2.</p>
<p>The multiplication by one million is simply to get the result on a scale that is easy to interpret. Otherwise, it
would be a tiny fraction. </p>
<p>Harvard (19.2) beats Stanford (2.2)…by a wide margin
Harvard is more attractive to California students than Stanford is to Massachusetts students. </p>
<p>Here are more scores:
Cornell (6.3) edges Duke (6.1)
Dartmouth (8.0) beats Rice (1.8)
Princeton (15.1) triumphs over Notre Dame (6.5)
Brown (4.7) squeaks by Vanderbilt (3.7)
Northwestern (5.5) upsets Harvard (5.4) in overtime </p>
<p>Just for fun, I’ll post the entire table of “box scores” one column at a time.
For this purpose, I considered Georgetown to be in Virginia.</p>
<p>I’ll start with Georgia.</p>
