"There's a statistics boom happening right now," but not many business people can actually use statistics effectively. More than academic correctness, what business people need is a practical way of thinking and "extremely easy-to-understand" statistical methods they can use starting tomorrow. This book is aimed at humanities-oriented employees who are allergic to math. By working through concrete examples and using common numbers from the business world, this practical guide helps readers acquire "usable" statistical thinking by the time they finish reading it, making it a valuable resource for business practice.
