Alex Reinhart

I’m an associate teaching professor of Statistics & Data Science at Carnegie Mellon University. I help lead the Teaching Statistics Group studying how students learn statistics and how we can teach better, and conduct research on the COVID-19 response, including the largest public health survey ever conducted.

You should read my book Statistics Done Wrong, the woefully complete guide to the many ways that statistics is abused in science. Now available in print, published by No Starch Press!
