Determining Sample Size Page 2 - Tarleton
www.tarleton.eduIf 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. Where n is the sample size and N is the population size.
