WebApr 6, 2024 · In general statistics when taking large samples relative to the population, for example with a sample size of 500 and a population size of 1000, we need to calculate the variance with a fixed population correction factor which I believe is $(1-\frac{n}{N})\frac{\sigma^2}{n}$. The standard deviation is then the square root. WebMay 21, 2024 · The finite population correction (FPC) factor is often used to adjust a variance estimator for surveys sampled from a finite population without replacement … The Finite Population Correction Factor (FPC) is used when you sample without replacement from more than 5% of a finite population. It’s needed because under these circumstances, the Central Limit Theorem doesn’t hold and the standard error of the estimate (e.g. the mean or proportion) will be too big. In basic … See more The general formula is: 1. N = population size, 2. n = sample size. If the calculated value for the FPC is close to 1, it can be ignored. As the sample size falls under 5%, the value becomes somewhat insignificant (an FPC … See more Basically, place the correction at the end of the formula you want to use.
