This is a great book that I recommend everyone to have, from beginners to advanced data and/or business analysts. It covers a wide range of topics, presented in a rigorous but, at the same time, very interesting way. Most of the topics covered are augmented with some real life examples as well as good quality images which give the book a special flavour. This book is now part of my "often consulted books" shelf.
