Design Sensitivity: Statistical Power for Experimental Research

By Mark W. Lipsey

Book Overview

Whether in the laboratory or while doing fieldwork, all researchers face an important challenge - designing research that will have sufficient sensitivity to detect those effects it purports to investigate. Sample size, validity, and sensitivity, experimental error, subject variability and the type of statistical analysis all influence the sensitivity of a research design.

In this volume Lipsey examines the concept of design sensitivity and explains statistical power and the elements that determine it. Through careful explanations and selection of examples he explores a variety of topics: factors that degrade design sensitivity, effect size parameters and approaches to assessing it, how to estimate statistical power for various statistical tests, and the special problems statistical power poses for treatment effectiveness research. This book is a vital resource for evaluators, methodologists, statisticians, psychologists, public health professionals and educators.

Great book for those that can understand the material

I thought this was a great book. The information presented in the book should form the foundational knowledge of a researcher or evaluator. However, the book does require a certain level of sophistication on the part of the reader. While the prose are clear and concise, readers who do not possess a modest amount of statistical knowledge may get lost.
