Designed for the nontechnical researcher or generalist, this text provides the reader with a good understanding of sampling principles. The author gives a detailed, nontechnical description and guidelines with limited presentation of formulas to help reach basic research decisions, such as when to choose a sample vs. census and nonprobability vs. probability sampling as well as how to select sample size and sample type. Intended for the social and behavioral sciences, Sampling Essentials is appropriate for undergraduate students, graduate students, and research practitioners.
