nice video on t-tests

I have found this really excellent U-tube video on the T-test and P-values. It takes you on a really nice slow tour of the T-test and P-values, with some nice visual examples.

NB, the main example the guy shows he calls the 'independent samples t-test'. This is also sometimes called the 'two sample t-test'.

Also, make sure you watch all the way to the end-  the last thing dealt with is how to write the results of a t-test down - this will be very useful to you for your 109 work!!

Enjoy!
