Introductory Statistics for the Behavioral Sciences

by Joan Welkowitz, Robert B. Ewen, Jacob Cohen

This book represents the efforts of three authors who have jointly accumulated many years of experience in statistical procedures through teaching and research efforts. Our purpose has been to introduce and explain statistical concepts and principles clearly and in a highly readable fashion, assuming minimal mathematical sophistication but at the same time avoiding a "cookbook" approach to methodology. We have attempted to present a broader outlook on hypothesis testing than is customary by devoting an entire chapter to the much neglected concepts of statistical power and the probability of a Type II error. To our knowledge, this is the first time that power tables that can easily be used by beginning students of statistics have been included in an introductory statistics textbook.
