Query: A well written book

I purchased this book to review stats for a course I'm taking in graduate school. The title says it all. This book is written in a very conversational way. As a result, the concepts are easy to understand. Unlike most text books, this book isn't trying to overwhelm you with information. The book simply explains the concept and it's usage, using some easy to understand examples. I highly recommend this book.
