Statistics podcasts on Youtube

This fellow, Keith Bower (at KeithBower.com) has some useful podcasts about statisitical tests which we began discussing when we went to the computer lab just before Thanksgiving. Here's one for the P-value: http://www.keithbower.com/Basic%20Stats/What%20is%20a%20p-value.htm. "If the P-value is low, the null hypothesis must go."

The correlation coefficient, or Pearson's r: http://www.keithbower.com/Basic%20Stats/correlationcoefficient.htm. The measure of the strength of the linear relationship, or association, between two variables, and ranges from -1.0 to +1.0.
