Query: Not worth the money

This book is nowhere near as rigorous as most college statistics classes will be, and serves little purpose. It has many problems (a plus), but the subjects are not treated as in-depth as they should be. This is fine, I suppose, for a basic understanding of probability and statistics, but for readers who want to go beyond that, this is not worth the money. Buy DeGroot instead, it's much better.
