The sample size formula for the infinite population is given by. Another sample size formula is. Sample Size will be Sample Size 20.
Mathematically it is represented as t x m s n.
If the population is N then the corrected sample size should be 186N N185. Plug in your Z-score standard of deviation and confidence interval into the sample size calculator or use this sample size formula to work it out yourself. In practice the sample size used in a study is usually determined based on the cost time or convenience of collecting the data and. If the population is N then the corrected sample size should be 186N N185.
