Adjusting Sample Size For Finite Population. Sep 17 2020 Luckily this doesnt tend to be a problem if the sample size is less than 5 of the total population size. The sample size n 0 can be adjusted using Equation 3.
QUESTIONWhen the proportion of sample size to population size nN is greater than 5 the finite population correction factor is used to adjust the standar. For most situations the population is so large typical sample sizes are far too small to worry about the need for the FPC. Where sigma is the population standard deviation of the underlying distribution.
However when the sample size is larger than 5 of the total population its best to apply a finite population correction often abbreviated FPC which is calculated as.
For most situations the population is so large typical sample sizes are far too small to worry about the need for the FPC. Z From the z -table we have the value of confidence level that is 258 by applying given data in the formula. N2 600 as r in the formula the ratio n2n1 was set to 2 can I then apply the FPC to the total sample size to correct for the finite population. The N-nN-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.
