Adjusting Sample Size For Finite Population. 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.
Where sigma is the population standard deviation of the underlying distribution. The sample size n 0 can be adjusted using Equation 3. Z Z statistic for a level of confidence of 95 196 P expected prevalence 105 d precision.
The sample size n 0 can be adjusted using Equation 3.
Using the finite population correction factor in Equation. This video demonstrates how to calculate the sample size with a finite population using Microsoft Excel. In case the population size is very large but the exact number is not known then use 100000 because the sample size doesnt change much for populations larger than that. You may adjust sample size for t-distribution applied by default finite population or clustering by clicking the Adjust button below.
