Books

 Math Mammoth Statistics & Probability A worktext with both instruction and exercises, meant for grades 5-7. The book includes lessons on reading and drawing different graphs including circle graphs and stem-and-leaf plots, mean, median, mode, and range, and simple probability.

 How to Lie With Statistics A bit dated, but fun! This book remains relevant as a wake-up call for people unaccustomed to examining the endless flow of numbers pouring from Wall Street, Madison Avenue, and everywhere else someone has an axe to grind, a point to prove, or a product to sell. Statistics are rife with opportunities for misuse, from "gee-whiz graphs" that add nonexistent drama to trends, to "results" detached from their method and meaning, to statistics' ultimate bugaboo--faulty cause-and-effect reasoning.

 How To Lie With Charts The main focus of How to Lie with Charts is on the principles of persuasive-and undistorted-visual communication. It's about careful thinking and clear expression. So don't blame the computers. People are running the show.

 A Mathematician Reads the Newspaper In this book the author reveals the hidden mathematical angles in countless media stories. His real life perspective on the statistics we rely on and how they can mislead is for anyone interested in gaining a more accurate view of their world. The book is written with a humorous and knowledgeable style that makes it great reading.
