Why, then, is statistics so important? All business disciplines can be analyzed with statistical principles. Statistics make it possible to analyze real world problems with actual data, so that we can understand if our marketing strategy is really working, or how much a company should charge for its products, or any of a million other practical questions.

Without a formal framework for analyzing these types of situations, it would be impossible to have any confidence in our results. This is where the science of statistics comes in. Far from being an overbearing collection of equations, it is a logical framework for analyzing practical business problems with real-world data.

About This Book

All business degrees require at least some statistics courses, and there’s a good reason for that! All business disciplines are empirical by nature, meaning that they need to analyze actual data to be successful. The purpose of this book is to:
✓ Give you the principles on which statistical analysis is based
✓ Provide you with many worked-out examples of these principles so that you can master them
✓ Improve your understanding of the circumstances in which each statistical technique should be used

As a For Dummies title, this book is organized into modules; you can skip around and learn about various statistical techniques in the order that suits you. In cases where the contents of a chapter are based on previous readings, you are guided back to the original material. Along the way, there are many helpful tips and reminders so that you get the most out of each chapter.
I explain each equation in great detail, and all key terms are explained in depth. You will also find a summary of key formulas at the back of the book along with important statistical tables.

This book can’t make you an expert in statistics, but provides you with a way of improving your knowledge very quickly so that you can use statistics in practical settings right away.
