Statistics has permeated every aspect of our lives--it shapes our attitudes and determines the things we buy. John L. Campbell has for this reason written this book so that the average person can become statistically literate. This book is for professionals who need to better understand the concepts behind statistics but not so much about the calculations. In perhaps the only book on statistics without a single equation, graph, or table, Campbell advises the reader to question statistics that are overly vague or precise.
