Sažetak:(from the jacket) How many subjects? introduces a simple technique of statistical power analysis which allows researchers to compute approximate sample sizes and power for a wide variety of research designs. Because the same technique is used with only slight modifications for different statistical tests, researchers can easily compare the sample sized required by different statistical tests, researchers can easily compare the sample sizes required by different designs and tests to make cost-effective decisions in planning a study. These comparisons, emphasized throughout the book, demonstrate some important principles of design, measurement, and analysis that are rarely discussed in courses or textbooks. This book therefore serves not merely as a "how-to" reference for sample size calculations, but also as a guide to some general principles of cost-effective research.
