[Edu-sig] Some interactive Python tutorials on basic stats, possibly useful for teaching

Very nice! I taught introductory stat in night school at Boston 
University -- it was a "one chapter ahead of the students" kind of gig. 
This kind of tool would have extremely valuable for helping students to 
develop an intuition for statistical concepts.

Working with the "correlation" program (Python 2.6, Win/XP SP3 box), I 
found that I needed to insert the statement

   pylab.draw()

at the end of the clear_the_figure_and_empty_points_list() function.

Again, many thanks!
