Wise Use of Null Hypothesis Tests 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 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.
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.
