I had to buy this book for a graduate-level statistics course. I thought it was kinda silly at first, but it has been a great tool. It has beautiful graphics with fantastic step-by-step instructions and explanations on the whats and whys of tables and figures. I've made some great infographics with the help of this book. Highly recommend for anyone who ever has to present data in some form of fashion.

This book is a great resource. I need to manipulate data for work and present results in PowerPoint and didn’t have much experience. I’ve found this book very straightforward and well organized.
