Thank you very much. You're a life saver. Saved me a great deal of confusion. You made it simple and saved me a whole day's worth of going through the readings again.

I enjoy your videos but I enjoy your perspective on teaching statistics more than you teaching statistics. In other words.... Teach us how to teach stats?
