<p>spark09223 - The methodology is not flawed: 25 cr + 25 m then 75 cr + 75 m of enrolled students. We suspect there’s a mistake associated with bad data involved. The 25/75% range obtained using this methodology would be with in 20 points of the range of the composite score (very easy to prove mathematically). What we believed happened here is that usnews accidentally used the 25 cr + 25 m then 75 cr + 75 m of admitted students for UChicago. Our suspicion arose from the fact that other top 20 schools’ reported number is within 20 points of usnews’, while UChicago’s is 50 points away. The additional 30 points in UChicago’s case is believed to due to use of data for admitted students instead of enrolled students. We are currently awaiting usnews’ response to our inquiry before making any definite conclusions.</p>
