I teach Statistics for a living, and this book replaced the book by Weiers, a move that I have berated the folks that do our purchasing ever since. The other Stats lecturer felt the same, and we have ended up using old copies of the prior book.
For example, the book gives a miserly single page to explain Quartiles, and has very little in the way of examples that are helpful.
If you HAVE to have it because your school dictates, you have to have it, but if you want to buy a book for the purpose of teaching yourself Stats, look elsewhere.

I've taken various probability/statistics classes as an undergrad at VA Tech, and as a grad student at GMU and MIT. This book is without question the best I have seen - by a long shot. Further, it provides the only thorough and rigorous explanation for hypothesis testing I have ever seen.

The theory and end of chapter exercises are as straightforward, clear and concise as you will get. The only manner by which this book could be improved would be by the inclusion of a rigorous proof as to why considerations regarding the degrees of freedom (dof) require that some equations have /n as a denominator while others have /(n-1).

the inside of the book is almost brand new~and the price is quite cheap~I like it very much~

This is a very useful book for my study. I use it to learn a lot of knowledge. you may try it.
