Description
<i>Wise Use of Null Hypothesis Tests </i>is a user-friendly handbook meant for practitioners. Rather than overwhelming the reader with endless mathematical operations that are rarely performed by hand, the author emphasizes concepts and reasoning. In <i>Wise Use of Null Hypothesis Tests</i>, 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. 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 <i>Wise Use of Null Hypothesis Tests</i>, 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.
