The confidence interval depends on the sample size, n (the variance of the sample distribution is inversely proportional to n, meaning that the estimate gets closer to the true proportion as n increases); thus, an acceptable error rate in the estimate can also be set, called the margin of error, , and solved for the sample size required for the chosen confidence interval to be smaller than e; a calculation known as "sample size calculation.". Taking the commonly used 95% confidence level as an example, if the same population were sampled multiple times, and interval estimates made on each occasion, in approximately 95% of the cases, the true population parameter would be contained within the interval.

Enter your population or sample observed values in the box above. Webinars Learn from expert customers with insider tips. To do this, use the confidence interval equation above, but set the term to the right of the sign equal to the margin of error, and solve for the resulting equation for sample size, n. The equation for calculating sample size is shown below. Unfortunately, unless the full population is sampled, the estimate p most likely won't equal the true value p, since p suffers from sampling noise, i.e. https://www.calculatorsoup.com/calculators/statistics/statistics.php.
