Alex Reinhart

I’m an assistant teaching professor of Statistics & Data Science at Carnegie Mellon University. I work on statistical models to understand and predict where events occur, while also helping lead the Teaching Statistics Group study how students learn statistics and how we can teach better.

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!
