Wise Use of Null Hypothesis Tests (eBook)

Few students sitting in their introductory statistics class learn that they are being taught the product of a misguided effort to combine two methods into one. Few students learn that some think the method they are being taught should be banned. Wise Use of Null Hypothesis Tests: A Practitioner's Handbook follows one of the two methods that were combined: the approach championed by Ronald Fisher. Fisher's method is simple, intuitive, and immune to criticism. Wise Use of Null Hypothesis Tests is also a user-friendly handbook meant for practitioners. Rather than overwhelming the reader with endless mathematical operations that are rarely performed by hand, the author of Wise Use of Null Hypothesis Tests emphasizes concepts and reasoning. In Wise Use of Null Hypothesis Tests, the author explains what is accomplished by testing null hypotheses-and what is not. The author explains the misconceptions that concern null hypothesis testing. He explains why confidence intervals show the results of null hypothesis tests, performed backwards. Most importantly, the author explains the Big Secret. Many-some say all-null hypotheses must be false. But authorities tell us we should test false null hypotheses anyway to determine the direction of a difference that we know must be there (a topic unrelated to so-called one-tailed tests). In Wise Use of Null Hypothesis Tests, the author explains how to control how often we get the direction wrong (it is not half of alpha) and commit a Type III (or Type S) error. - Offers a user-friendly book, meant for the practitioner, not a comprehensive statistics book - Based on the primary literature, not other books - Emphasizes the importance of testing null hypotheses to decide upon direction, a topic unrelated to so-called one-tailed tests - Covers all the concepts behind null hypothesis testing as it is conventionally understood, while emphasizing a superior method - Covers everything the author spent 32 years explaining to others: the debate over correcting for multiple comparisons, the need for factorial analysis, the advantages and dangers of repeated measures, and more - Explains that, if we test for direction, we are practicing an unappreciated and unnamed method of inference

Frank S. Corotto earned his bachelor of science in biology at Lafayette College in Pennsylvania, his master of arts in biology at Boston University, and his doctorate in biological sciences at the University of Missouri-Columbia. He worked as a post doc at the University of Utah's Department of Physiology then went on to teach biology at North Georgia College, later renamed North Georgia College & State University, for 17 years and at the University of North Georgia for eight years. While initially a neurobiologist, he researched in other fields including animal behavior, plant reproduction, and ciliate feeding selectivity. Because of his interest in experimental design, he discovered a primary literature on null hypothesis testing that ran counter to what is in traditional statistics books. The result is Wise Use of Null Hypothesis Tests: A Practitioner's Handbook.
