PASS Sample Size Software 6-1 NCSS, LLC. All Rights Reserved. Chapter 6 Introduction to Power Analysis Overview A Statistical test s Power is the probability that it will result in Statistical significance. Since Statistical significance is the desired outcome of a study, planning to achieve high Power is of prime importance to the researcher. Because of its complexity, however, an Analysis of Power is often omitted. PASS calculates Statistical Power and determines sample sizes. It does so for a broad range of Statistical techniques, including the study of means, variances, proportions, survival curves, correlations, bioequivalence, Analysis of variance, log rank tests, multiple regression, and contingency tables. PASS was developed to meet several goals, including ease of learning, ease of use, accuracy, completeness, interpretability, and appropriateness.
