This is a fascinating introductory book on statistics that discusses a
fairly standard set of themes in methods, statistics, and statistical
graphics with an absolute minimum of math, taking a broad array of
well-chosen examples mostly from newspapers. If you use this book in an
introductory statistics class and you still don’t succeed in convincing 80%
of your students that learning statistics is important and is actually a lot
of fun (even if you don’t plan a career as a researcher), it may be time to
change professions.
The book excels at “why” but does not go very deeply into
“how”. For instance, it has good discussions of the pros and
cons of experimental studies versus observation studies, the difference
between significance and relevance, etc. These themes are more important but
harder to convey than the (somewhat boring) discussions of, say, two-sample
t tests with or without the assumption of a common variance. For this
reason, you might want to emphasize those first concepts to your students as
important themes. If you agree, you may want to take a look at this book.
