Our society is churning out more numbers than ever before, whether in the form of spreadsheets, brokerage statements, survey results, or just the numbers on the sports pages. Unfortunately, people’s ability to understand and analyze numbers isn’t keeping pace with today’s whizzing data streams. And the benefits of living in the Information Age are available only to those who can process the information in front of them. What the Numbers Say offers remedies to this national problem. Through a series of witty and engaging discussions, the authors introduce original quantitative concepts, skills, and habits that reduce even the most daunting numerical challenges to simple, bite-sized pieces. Why do the nutritional values on a Cheerios box appear different in Canada than in the U.S.? How is it that top-performing mutual funds often lose money for the majority of their shareholders? Why was the scoring system for Olympic figure skating doomed even without biased judges? By anchoring their discussions in real-world scenarios, Derrick Niederman and David Boyum show that skilled quantitative thinking involves old-fashioned logic, not advanced mathematical tools. Useful in an endless number of situations, What the Numbers Say is the practical guide to navigating today’s data-rich world. Non sono state trovate descrizioni di biblioteche |

The authors use examples from contemporary politics, which not only illustrate the woeful innumeracy of many commentators but also the maxim that you should never assume malevolence when incompetence is a valid explanation – sort of a variant on Occam’s Razor. One interesting point is the authors actually concur with the Washington Post columnist who criticized requiring all high school students to take algebra; they propose “practical math” type courses instead. Possibly not a bad idea; the kind of numerical reasoning they give examples of would benefit most people more than algebra. Alas, I suspect this sort of thing would somehow degenerate into a Common Core-type math fiasco.
Worth a browse; a quick read and, perhaps surprisingly no math beyond the basics. ( )
