I bought Statistics for Dummies to help with the statistical portion of my Master's thesis. Somehow, I had managed to get through college and grad school without taking a statistics course. Unfortunately, this book was almost no help with learning statistics at all. The reason, it isn't intended to help you do statistics; it is intended to help you interpret them. It does a very good job at it's real purpose—helping you make sense of the statistics bandied in the new media.Journalists tend to report on relative risk because they are easy to say and can sound impressive. For example: Say one person per billion in the population at large typically experiences having their brains blow out the back of their head when they sneeze. Now say that two people per billion have that happen when they are filling up their cars with premium fuel, but there is no difference in people who fill up their cars with regular. That means you are 100% more likely to sneeze and blow out the back of your head while filling your car with premium. So you should never use premium fuel! Right?What journalists would ignore in the previous fallacious scenario is that your actual risk is only two in a billion. But a 100% increase in risk sounds a lot more interesting and scary, doesn't it. Sigh.The book is very readable and even humorous at times. Humor is a major accomplishment in a subject as dry as this one. One of the most important lessons it teaches is to distrust relative risk comparisons.
