Determining Sample Size

This pocket guide to Determining Sample Size shows social work students, educators, and researchers how to prevent some of the mistakes that would result from a wrong sample size decision by describing and critiquing five main approaches to determining sample size. In concise, example-rich chapters, Patrick Dattalo covers sample-size determination using power analysis, heuristics, confidence intervals, computer-intensive strategies, and ethical or cost considerations, as well as techniques for advanced and emerging statistical strategies such as structural equation modeling, multilevel analysis, repeated measures MANOVA and repeated measures ANOVA. He also offers strategies for mitigating pressures to increase sample size when doing so may not be feasible. The links featured here go to an excellent variety of external resources, and are listed in two sections: by statistical procedure, and by chapter in the book.
