Overview

Do you have a secret? Are you unsure what you accomplish by testing null hypotheses? Do you ask your colleagues which test to use, perhaps after you have collected the data? Are you perplexed by your statistics book with its technical jargon, italicized symbols, and endless mathematical operations you will never perform by hand? With Null Hypothesis Testing: Demystified! you can be the expert. You can learn the logic behind testing nulls, the simple principles that underly the mathematics of the tests, why different types of tests are required for different types of data, how to design research studies around the null hypothesis tests you will perform, and how to draw the right conclusions from those tests. It's easy!You can learn why many nulls that cannot possibly be true, but it is important to test them anyway! You can learn why P is not the probability of a type I error, why a null hypothesis is not always a statement of no difference, why the alternative or alternate hypothesis (as it is usually defined) is completely useless, why significance is so widely misunderstood that it would better to use another word, why the null should not be accepted just because P > alpha, and more. The practice of testing nulls has been fiercely debated for decades. With Null Hypothesis Testing: Demystified! you can learn what would be the best outcome of that debate-wise use.Null Hypothesis Testing: Demystified! is not a substitute for a traditional statistics book, but rather a complement to such a book. The author of Null Hypothesis Testing: Demystified! uses prose in place of italicized symbols, real world examples of null hypotheses, and only a few mathematical examples to illustrate important points. Null Hypothesis Testing: Demystified! emphasizes concepts and practical application. You really can be the expert, and it is all remarkably simple!
