Before you can calculate a sample size, you need to determine a few things about the target population and the sample you need: 1.size is 1,000, so the sample size recommended is 200=1;000 = 0:2, or 20%, of the population size. In this case, the required sample size may be reduced somewhat, since the sample size is a considerable portion of the total population. But if the sample size is less than, say, 5% of the population size, the above formula holds. The reason for this 1) the precision with which they can estimate a parameter given their sample size, 2) the sample size that they need to estimate a parameter with a certain precision, 3) the minimum detectable effect size given group sizes, and. 4) the required group sizes given the minimum detectable effect size.The sample size necessary to obtain a desired level of statistical power depends in part on the population value of the effect size, which is, by definition, unknown. A common approach to sample-size planning uses the sample effect size from a prior study as an estimate of the population value of the effect to be detected in the future study.In the end, researchers have to balance their ideal sample size, which is very large, with real-world issues, which demand a smaller sample.
