I bought this book to be used in addition to my college coursework. This book's explanations and examples helped reinforce what I had learned in class by applying the lessons to real world scenarios. For example, my stats professors like to test our knowledge by asking us about the results of some random study; we look at the numbers from the study and decide whether or not they are valid. In our final exam, one question involved a study that attempted to predict how many goals a hockey player was able to make in a given season. I remembered Ellenberg's explanation of "the hot hand" in the NBA and I was able to grind the hockey study into dust. I not only aced the exam, but my professor wrote an email saying that no student had dissected this study so thoroughly. I also passed one of our hardest homework assignments by successfully arguing that the study we had performed was "torturing the data", and we did not really have significant results. All of this information was before the half-way point of the book. There's so much more to learn.<br><br>I recently graduated, and I still listen to this audio book because the information is so rich and varied. It's a really easy way to keep your general skills sharp. This books isn't full of numbers and symbols, so I wouldn't recommend it for people who need to learn the actual math.
