    Its really not much at all, its just the central limit theorem, which is basically getting the mean of the means of many samples, and the conditions in which you can use it, something about n> 30 or can use if n<30 if underlying population normally distributed! And it changes your standard deviation to sigma over root n (I think) I can check my notes tomorrow and make sure thats right :L bit sleepy now to even know if that's right it could be the biggest load of crap ever :pac: :pac:
