"...the best example of synergy since Tracy and Hepburn"
-- Chris Olsen, AP Stats listserve, Dec 3, 2003.

Fifty Fathoms is a collection of fifty demonstrations that try to get at some of the tough ideas in an introductory statistics course. The book comes with a CD-ROM packed with cool files; the printed pages tell you how to use them.

And why are they so cool? Because they use Fathom Dynamic Statistics (TM) software from Key Curriculum Press.

The CD includes a limited-use edition of Fathom so you can use the demos. But if you own a full-featured Fathom—even a Student version—you can customize these demos, and make better use of them.

The demos in the book run the gamut from first-week stuff like the meaning of mean and median to really confusing topics such as the power of hypothesis tests.

Note: This book is for Fathom Version 1. For the Version 2 edition, please visit Key Curriculum Press.
