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.
I did the pre-Coursera ML class and pre-Udacity AI class at the same time (both professors went on to for the respective companies after the experience), got two certificates with a reasonable grade, being a father and having a dayjob. I can attest to having fairly average intelligence by LW standards. (So yes, I think it's quite doable)
