This book is wonderful, albeit a bit dense. It's a long read but it's invaluable if you want to be knowledgeable about mathematical reasoning and statistics. I've always prided myself on making sure that I have an accurate picture of the world and the information that I'm being given. Not having a vast knowledge of statistics makes that difficult, especially when people tend to throw them around to "prove" their points. This book tells you how to verify the authenticity of the stats and how those stats can and should be used along with what they can actually prove. Without this knowledge, you're pretty much at the mercy of any random misrepresented statistic. E.g. I recently watched the documentary "What the Health" and I was stricken by the statistic that eating a lot of processed meats increased your potential for colon cancer by 20% but after looking into the statistic I realized that it only increased your "absolute" rate of cancer by 1% (from 5% to 6%), which would constitute a 20% increase 1 being 20% of 5, but vastly misleading in the way that it was presented. The only drawback to the book is that it's so dense and you can tell it was written by a mathematician. It's a good book to make your way through gradually.
