Conventional statistical methods have a very serious flaw. They
routinely miss differences among groups or associations among
variables that are detected by more modern techniques, even under
very small departures from normality. Hundreds of journal articles
have described the reasons standard techniques can be
unsatisfactory, but simple, intuitive explanations are generally
unavailable. Situations arise where even highly nonsignificant
results become significant when analyzed with more modern methods.
Without assuming the reader has any prior training in statistics,
Part I of this book describes basic statistical principles from a
point of view that makes their shortcomings intuitive and easy to
understand. The emphasis is on verbal and graphical descriptions of
concepts. Part II describes modern methods that address the
problems covered in Part I. Using data from actual studies, many
examples are included to illustrate the practical problems with
conventional procedures and how more modern methods can make a
substantial difference in the conclusions reached in many areas of
statistical research. The second edition of this book includes a
number of advances and insights that have occurred since the first
edition appeared. Included are new results relevant to medians,
regression, measures of association, strategies for comparing
dependent groups, methods for dealing with heteroscedasticity, and
measures of effect size.
