Finite population sampling
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.

WebSampling from a Finite Population: Interval Estimation of Means, Proportions and Population Totals Jerry Brunner March 21, 2007 Most of the material in this course is based on the assumption that we are sampling with replacement, or else sampling without replacement from an “infinite population” (definitely a theoretical abstraction.
WebFinite Population Correction For Proportions If the population is small then the sample size can be reduced slightly. This is because a given sample size provides proportionately more information for a small population than for a large population. The sample size (n 0) can be adjusted using Equation 3.
