Find Minimum Sample Size. Note that if some people choose not to respond they cannot be included in your sample and so if non-response is a possibility your sample size will have to be increased accordingly. N 1960 004 2 05 1 05 60025 This is the minimum sample size therefore we should round up to 601.
If you want to find instead a confidence interval for the mean please use this confidence interval calculator. So you need to take a random sample of at least 211 college students in order to have a margin of. The sample size references the total number of respondents included in a study and the number is often broken down into sub-groups by demographics such as age gender and location so that the total sample achieves represents.
Sigma σ is provided and the significance level is specified we can compute the minimum required sample size that will lead to a margin of error less than or equal to the one specified by using the following formula.

If you are dealing with a population mean instead of a population proportion you should use our minimum required sample size calculator for population mean. N ge left frac z_c sigma Eright2 n. If the population is N then the corrected sample size should be 186N N185.
