WebFinite population correction (FPC) The formula given above for the standard error assumes that the population is infinite. Nonetheless, it is often used for finite populations when … Formula. The general formula is: FPC = ((N-n)/(N-1)) 1/2 Where: N = population size, 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 is .998 for a sample of 50). See more 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, … 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.
