Sample size question

There's a story behind this, but I'm doing a little personal project and I'm trying to make a case about something statistically. I've taken an intro to stats class, and either I never learned what I need, or I cannot remember/find it.

Anyways, I have a population of 6139 that is not normally distributed, and from which I can randomly draw as many samples as I want (and they will be random). What is the minimum number of items I need to draw for significant result?

Re: Sample size question

There is no exact number. The more samples you draw, the more significant will the answer. Also are you looking for a good estimate of the distribution or will you be satisfied with good estimates for the mean and variance.

Re: Sample size question

Sorry, yes, I wanted a number that would give me a very good estimate of the distribution without having me simply go through all of the individual samples.

Thanks.
