Sufficient Sample Size for Binomial Distribution

Hey guys, I was just wondering how I should go about calculating the minimum sample size required to achieve a fairly strong significance in my test results. I must admit, my statistics is quite out of touch, and I would *love* a really simplified explanation.

Thanks all.

Re: Sufficient Sample Size for Binomial Distribution

For the binomial distribution, ? = ?{p(1-p)/n}, where ? is the standard deviation, n is the sample size, and p is the probability of success. Therefore given p, you choose n based on how good you want your estimate to be.
