<p>LSAT Mean = 151
SD = 7</p>
<p>The top 25 schools listed on the previous page range from 161-165. Let’s choose one for each score value.</p>
<p>Georgetown 161
Rice 162
Dartmouth 163
Williams 164
Yale 165</p>
<p>Let’s convert these scores into Z scores and compare them to SAT Math mean scores (estimated by using the median since I can’t find mean) and see if these schools are under/over/matching input variables of students.</p>
<p>School LSATZ SATMZ Difference</p>
<p>Georgetown 1.43 1.64 0.21
Rice 1.57 1.81 0.24
Dartmouth 1.71 1.81 0.1
Williams 1.86 1.68 -0.18
Yale 2 1.94 -0.06</p>
<p>Now, if you look at these numbers you can see they’re all over the place. In fact, a linear best-fit only gets an R^2= .39.</p>
<p>Now either SAT Math is a bad predictor of LSAT score (not sure, but if both/either are considered good predictors of intelligence they should correlate), or there is a difference in what school you attend, and it’s not always small.</p>
<p>Either some of these schools are attracting students that are smarter than other schools (by quite a bit) by some measure that’s not SAT math, something is going on different once you’re in each of these schools which has an effect, etc, etc.</p>
<p>Importantly, for the most part, schools that are annually at the top (Yale, Williams, Dartmouth) appear to be doing better at matching inputs than other schools. This at least suggests that no harm is being done and smart students are just as smart going in as out when it comes to standardized test ability.</p>
<p>Of course, this is all rudimentary stupid math done on five data points, but I’d say that LSAT scores this “low” are not really blemishes on top schools.</p>
