Back in 2014-15, Duke averaged 7.5 and Wash U was 14.
Duke recently went from 8 to 12 and now back to 9.
Wash U had risen to 18-19 for a few years and now back down to 14 after being 16 last year.
It would be interesting to decipher what contributed to Wash U’s five point drop but you’d also wonder what contributed to its five point increase. I guess it had to do with a super-charged focus on need based aid.
Since 2014, the three schools with the highest annual standard deviation have been Alabama, Howard and Tulsa. In 2014-15, Tulsa and Alabama were tied with an average rating of 87. They’re now roughly in the 140s. Howard seemed to greatly benefit from a change in ranking criteria focused on outcomes relative to socio-economic status and is now in the 80s after being in the 140s in mid-2010s.
