Statistics for Aff Marketing?

[yubrew]

Took Probability and Statistics a long ass time ago, and don't remember much at all.

Now I'm trying to analyze a bunch of data from split tests and do some multi-variate testing. Any suggestions on short guidelines or resources for stats refreshers?

For anyone wanting to build their own A/B testing func: Z-test - Wikipedia, the free encyclopedia is really the only piece of statistics you need to implement.

multi-variate testing is great, but what exactly are you trying to test/find out?

That's not really true at all, z-testing can be pretty limited.

Z-testing only works when the population standard deviation is known, but 99.99% of the time in AM you'll only know the sample standard deviation, therefore:

Multi-variate, testing a bunch of factors at once. Different style lp's, color, page elements, etc.

Student T, thanks!

I think I just learned something. Thanks and sorry for the bad advice.

Excuse my ignorance, but please explain how this works and what we can determine from it for those who were getting high behind the bike shed instead of going to maths?
