This is a cookbook with many interesting recipes. The frame story concerns Fred, a 6-year-old math genius, and is an extended narrative where he has many adventures and finds opportunities to use statistics. The story is engaging, if unbelievable, and shows statistics in everyday but somewhat contrived contexts. The book is one in a series of books designed for self-study and aimed mostly at homeschoolers, but including some college level topics, such as this one.

The organization of the book is unusual, grouping ideas according to how the data is gathered or presented rather than by statistical test. The book includes an Emergency Statistics Guide, similar to the symptom guides found in family medical guides, that uses a decision tree to guide you to the correct test based on the properties of the data and on what you are attempting to find out. Very Good Feature: the book constantly alerts you to the samples sizes needed for a test to work reliably.

Limitations: This is definitely a cookbook, with minimal discussion of mathematics and little attempt to justify the recipes. It is not calculus-based, and assumes nothing past high-school algebra. You don’t even need to understand *e*, logarithms, or square roots, because the book guides you to use a calculator to figure anything involving these.The exercises, although all word problems, are simple and are for drill rather than to expand understanding. I believe the premise is that the reader will do statistics with this book as a handbook, and therefore does not need to rely on memory and so the book does not include a lot of drill. There is no real-world data and no real-world examples, although the examples are very simplified versions of real-world problems.

This book lists for about one-third the price of other introductory statistics texts. This comes from several factors: (1) it has about half as many pages as the competition; (2) it is printed in black and white on ordinary book paper, not in full color on slick paper; (3) it is sold primarily at retail through the web and has essentially no marketing costs. The page count is kept low primarily by not having many worked examples; there is essentially one fully-worked example per statistical test, with some more sketched examples in the exercises. To put the cost in perspective, if this had been a Dover reprint, it would probably list for about $25 in softcover, so $39 for a hardcover of a current book seems reasonable.

Bottom line: an intriguing approach to introductory statistics at a bargain price, that would be a good text for service courses. It should also work for intelligent readers who want to get an understanding of what statistics can do.
