Summary

In a pleasing and conversational tone, Sally Caldwell uses this brief introductory book to invite the reader to join her on a rewarding journey into the often-feared territory of statistics. Rather than emphasizing equations at the expense of understanding, STATISTICS UNPLUGGED gives readers a clear presentation of the material they need to gain a solid grasp of what is involved in the process of statistical reasoning. While avoiding unnecessary jargon, this book uses the process of repetition and cross-referencing chapters to underscore the important concepts. As a result, the user is led, step-by-step, along the path of statistical reasoning.
