Paperback small octavo, as new condition, figures, tables. 167 pp. A researcher's decision about sample size for a study has a big impact on the results, and it rests on numerous statistical and practical factors that can be difficult to assess. This pocket guide by Patrick Dattalo shows social work students, educators, and researchers how to prevent the mistakes that result from a wrong sample size decision by describing and critiquing four main approaches to determining sample size. Covers statistical power analysis, confidence intervals, computer-intensive strategies, and ethical and cost considerations, as well as emerging statistical strategies such as structural equation modeling, multilevel analysis, and repeated measures MANOVA.
