Finite population correction factor 中文

WebThe formula for the finite population correction factor is defined as follows: Here, n and N are sample size and population size. The formula shows that the numerator is always smaller than the denominator as n is greater than 1 for all the practical applications. This makes the correction factor to be always less than 1. The population ...

WebThe factor (1−n/N) is called the finite population correction (fpc). Intuitively, we make this correction because with small populations the greater our sampling fraction n/N, the … WebLet's make it look a little more friendly to the eyes: n = m 1 + m − 1 N. where m is defined as the sample size necessary for estimating the proportion p for a large population, that is, when a correction for the population being small and finite is not made. That is: m = z α / 2 2 p ^ ( 1 − p ^) ϵ 2.

WebThe (N-n)/(N-1) term in the finite population equation is referred to as the finite population correction factor, and is necessary because it cannot be assumed that all individuals in a sample are independent. For example, … WebThis is known as the finite population correction factor for the variance of the estimator (Kish, 1965). The variance of a sample mean is σ 2 / n, which for finite populations is multiplied by the finite population correction factor of the standard error: F P C = (N − n) (N − 1) where N is the size of the population, and n is the size
