Determining Sample Size Page 2 - Tarleton
Determining Sample Size Page 4 Suppose our evaluation of farmers’ adoption of the new practice only affected 2,000 farmers. The sample size that would now be necessary is shown in Equation 4. As you can see, this adjustment (called the finite population correction) can substantially reduce the necessary sample size for small populations.
