Query: oh man...

When a statistics book is written under the premise of "demystifying" and simplifying a complex subject starts off with a chapter on basic math, you know you are in trouble. True, the computation of statistics relies on formulas, but they will not help you understand statistics - in fact, students often learn statistics better when the focus is on the construction of concepts over time, not the memorization of random formulas, most of which will be forgotten in the long run.This book is not entirely useless, but there are so many other better books on statistics. I recommend skipping this math...I mean, statistics book and focusing on them.
