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.
