Email marketing soft

Where I work we do a lot of surveys and we have software that tells us if a sample size is statistically significant. But nobody can explain the parameters that affect this (e.g. does the size of the population matter?). Would really appreciate a simple explanantion. Thanks!

my boyfriend loves maths and he is away now and I can only email to him. I want to give him a maths software like game of life (by John Conway) what do you sugget?
and please don’t forget the link to download that software (for free) since I don’t have credit card.
and he alredy has MATLAB
thanks
