Here are the formulas used in our Sample Size Calculator: Sample Size ss = Z 2 * (p) * (1-p) c 2 Where:Z = Z value (e.g. 1.96 for 95% confidence level) p = percentage picking a choice, expressed as decimal (.5 used for sample size needed) c = confidence interval, ...
Factors of Sample Size Calculation How to Find Sample Size Example of Sample Size in Experiments Lesson Summary Frequently Asked Questions What is the formula for sample size? There are many formulas used for calculating sample size. One of the most common formulas used is Yamane's formula: n...
Asymptotic formulas for expected sample size savings in curtailed binomial tests are derived using a central limit theorem of Feller (1943). Exact results for the expected sample size savings and the forms of the one- and two-sided curtailed tests are reviewed. The small sample properties of ...
A formula is given for approximating the minimum sample size required in some binomial type problemsdistribution-free tolerance intervals satisfying one or two probability conditions and hypothesis testing for p satisfying two power conditions. The approximation requires a percentile from a chi-square ...
