For those of you who would like to get into the heavy stats side of data mining (or have accepted the fat that they probably have to), I just came across a great YouTube video channel thanks to Shailendra Kumar's blog, the current data mining lead at Woolworths (his blog is a great reas as well but a little more involved).

The StatisticsFun YouTube channel contains some really great videos with step by step explanations of statistical concepts including the below on regression analysis which is basically the mechanism behind the prediction of customer behaviour based on past transactions or the holy grail of data mining. How about watching a few stats videos of the Christmas break?
