"Good coverage of target populations and samples, and statistics of sampling. Logical progression through the material with good use of examples."

--Carol J. Lancaster, Medical University of South Carolina

How much is enough in your sample? What is the difference between a research question and a survey question? By exploring the answers to these questions, this book shows readers how to specify inclusion and exclusion criteria in a sample, select the appropriate probability and non-probability sampling methods, understand the sources of error in sampling, and calculate the response rate. New to this edition is coverage of sample size and power so that the reader can better understand the logic in determining the sample size to detect a difference if one exists. Filled with checklists and guidelines, this book will enable readers to select and use the most appropriate sampling methods for their survey.

"Fink provides detailed descriptions of inclusion/exclusion criteria, the logic in estimating standard errors and sample size determination, and the sources of sampling errors."

--Gerald Albaum, book review in Journal of Marketing Research
