This book was a complete deception.I'm completely lay to statistics. I can't understand many concepts, and I have never come into anybody who could explain them easily and clearly: neither at the University nor as PhD student. And what is worse, I have no time now to study statistics with ease.In my job, I should have more learning, but this has not been the case. I bought this book because I'm utterly confused. I'm still utterly confused.
This is a book for students of statistics. I'm NOT saying this is a bad book, it's full of examples (a bit boring for my taste), grades its difficulty, rakes the concepts, etc... But forgets a basic fact: the problem is understanding the concepts,and how to use each statistical tool or test, not the formulas. A clear example is "Chapter XXX: Chi-square distribution: you should read this chapter if you need to use the Chi-square distribution". Bright and clear.
Besides, it forgets that nowadays we use computers, most people use Excel, and they do all the dirty work, so the most important thing is to make us understand which is the RIGHT test to use in each case, preferrably in each software, not how the test works.
Buy this book if you want a tough basic knowledge of the matter and have time to spare. If you want to have your problems solved, ask your friend at the statistics department!
