A Primer on Sampling for Statewide Assessment.
Jaeger, Richard M.
This paper is a primer on sampling procedures for statewide assessment. The careful reader should gain substantial knowledge about the promises and pitfalls of sampling for assessment. The primer has three basic objectives: (1) to define terms and concepts basic to sampling theory and its application, including population, sampling unit, sampling frame, probability sampling procedures, estimate, population parameter and estimator, estimator bias, variance, mean square error and efficiency, and consistency; (2) to illustrate some of the ways sampling procedures can be used to achieve realistic assessment objectives; and, (3) to describe issues that arise when sampling procedures are used, and the factors that contribute to their resolution. Objectives two and three include discussions of simple random sampling, stratified random sampling, systematic sampling, cluster sampling, and matrix sampling. The appendix gives an example of an evaluation of alternative cluster sampling procedures. (SE)
