General statistical education is an utter failure

July 23, 2014
By

As if we need more evidence. The statistics community loves to think of our subject as highly practical and relevant to the general population. And this is true. The average person has a poor grasp of basic statistical thinking, even if he or she has taken one or more statistics courses. This is true, yet many in our community are in denial. Chapter 1 of Numbers Rule Your World deals…

An anthropological study shows why complete data designs are counterproductive

I saw Joe N.'s tweet asking me about a study of how professors spend their time, reported by Lisa Wade at Sociological Images.

The problem is, to teach it well is extraordinarily difficult. It’s very easy to teach a horrible statistics class where you spit back the […]
