Having taken some Udacity courses I do not expect it to be hard for average LW-er, and probably useful (I never took a decent stats course in college). There is no penalty for dropping out if it's too easy.
IIRC the course will have complementary python programming exercises, which is a good complement to learning pure math.
I want to become Stronger!
Udacity are running an Introduction to Statistics course starting on the 25th June 2012.
Many of us could stand to learn some more stats, I certainly could. This seems like a great opportunity!
It is mandatory for all LWers to enroll in this course.
Update: the last line was a joke. Obviously people are not finding it funny. Sorry.
