I am a graduate student/veterinary resident taking a statistics course. This book is not required for my class, but "recommended," meaning that the instructor more or less follows this book for our lectures.
Having never had any type of stats class at all, I was pretty concerned about this class. In some ways, I still am, but this book is helping. It is pretty easy to read, and, most of the time, with each new concept introduced, there is an example to follow in the text. There are also questions to test yourself at the end of each chapter. The answers to these questions are in the back with decent explanations so if you get stuck, you can take a peek and "work backwards."
Overall, a good book especially for its target audience. Most examples are animal related. FYI...stats is still not cool. :)
