"The Simplest way to ace Statistics." Are you taking a statistics class right now or very soon? I struggled with statistics even while I got my master's degree in math, and after teaching statistics myself, I know why: statistics books and websites suck! They are written by people who "get" math, not for people like us! I wrote the Practically Cheating Statistics Handbook so you don't have to struggle anymore. I've been giving my own students this material since I started teaching, and the students who use it never fail, and their average grade is one or two letter grades higher than other students in the same class. Dozens of TI-83 how-to articles are included! This edition of The Practically Cheating Statistics Handbook includes the TI-83 Companion Guide, giving you simple, step-by-step instructions for solving the most common statistics problems with the TI-83 calculator. The guide walks you through each problem type, telling you exactly what buttons to press without leaving out any details!
