Sampling fraction
In
sample size to population size or, in the context of stratified sampling, the ratio of the sample size to the size of the stratum.[1]
The formula for the sampling fraction is
where n is the sample size and N is the population size. A sampling fraction value close to 1 will occur if the sample size is relatively close to the population size. When sampling from a finite population
finite population correction (or finite population multiplier) of (N-n)/(N-1) may be used. If the sampling fraction is small, less than 0.05, then the sample variance is not appreciably affected by dependence, and the finite population correction may be ignored. [2][3]
