Why you should read this book

Turning Numbers into Knowledge 3rd edition

The world keeps getting more complex, but becoming a better problem solver can help you make sense of it all. Mastering the art of problem solving takes more than proficiency with basic calculations–it requires (among other things) understanding how people use information, recognizing the importance of ideology, learning the art of storytelling, and acknowledging the important distinction between facts and values.

Turning Numbers into Knowledge is a compelling introductory guide to these and other essential skills. Full of tools, tricks, and tips for solving problems in the real world, it will prepare you well to make independent judgments about the numerical assertions of others and to generate cogent and compelling analyses of your own.

The newly revised and updated third edition of this book teaches beginning analysts and students the art of using numbers for practical problem solving, revealing tools, tricks, and heretofore unwritten rules that the best real-world problem solvers know by heart.

Because of formatting issues with the Kindle app on iOS devices, we recommend that you read the Kindle version using Kindle previewer on Mac OS or using other Kindle devices, or go for the ePub version. We are working with Amazon to resolve those issues, but the book is graphically complicated and just won’t format properly in the current version of the Kindle app for iOS.  The ePub version works just fine on iOS iBooks.
