Sampling.

Abstract

Sampling problems arise in social research in the development of techniques of observation and measurement and in the analysis and interpretation of data. Fundamentally, they stem form limitations on the number, accuracy, and scope of observations, and their solution consists of finding the most effective way of conducting research under these restrictions. There is no universally "best" method of sampling; the technique must be designed to fit the particular circumstances of each situation. The technical problems of sampling are outlined in terms of the initial specifications, design, costs and resources, accuracy, operation, and use.
