Webof the two rv’s differ by the factor (N –n)/(N –1), often called the finite population correction factor. This factor is less than 1, so the hypergeometric variable has smaller variance than does the binomial rv. The correction factor can be written (1 –n/N)/(1 –1/N), which is approximately 1 when n is small relative to N. WebTo correct for the impact of this, the Finite Correction Factor can be used to adjust the variance of the sampling distribution. It is appropriate when more than 5% of the population is being sampled and the population has a known population size. There are cases when the population is known, and therefore the correction factor must be applied.
Web8.7 Estimation and Sample Size Determination for Finite Populations WebJul 28, 2024 · The Finite Population Correction Factor for the variance of the means shown in the standardizing formula is: Z = x ¯ − μ σ n ⋅ N − n N − 1. and for the variance of proportions is: σ p ′ = p ( 1 − p) n × N − n N − 1. The following examples show how to …
