### GCSE Statistics Revision

Right, here's a list (in no particular order) of stuff you need to do.

Will put some more links here if I have time.

basically the plan is to revise Crude&Standardised rates on Monday, generaly revision on tues and weds. Anything else you want me to go over, you can leave me a comment here.
