After All, Statistics is the Strongest Tool for Increasing Sales!
This book is for those who haven't studied statistics and want to get an idea of how to use it. Difficult statistical contents and mathematical formulas are intentionally skipped in order to give readers the gist. Therefore, you will not understand statistics just from this one book. Instead, this book is meant as an introduction, and by reading it you will be able to use basic statistics. If you want to follow more difficult formulas and understand them well, I recommend you to buy a more advanced book as a follow-up to this one.
