Regression to the Mean/The regression effect

Tuesday, October 17th, 20172:00 pm – 3:00 pm

Presented by: Jeff Witmer (Oberlin College)


Regression to the mean, also known as "the regression effect," is an important but sometimes overlooked topic in introductory statistics. We will discuss the regression effect and how to teach it. We will also consider a number of examples of the "regression fallacy," in which people who are ignorant of the regression effect make up ad hoc (and sometimes very misleading) explanations for what they see in data.
