Resource Description

Sampling

Ellen Taylor-Powell

This evaluation resource provides guidance on conducting sampling. It first addresses whether sampling is an appropriate evaluation tool for a particular program. Then it presents sampling for generalizability, or probability sampling, and talks about specific sampling strategies, including simple random sampling, systematic sampling, and stratified sampling. The resource also explores sampling for other purposes, or non-probability sampling, including quota sampling and purposeful sampling. The appendixes list references, a table of random numbers, and recommended sample sizes. (12 pages)
