This new edition helps readers to make sense of the numbers that they encounter: as consumers, voters, in business, and in school. Instead of focusing on mathematics and computations, the author explains the underlying logic of statistical analysis and problem solving, building one concept upon another to provide a solid framework for understanding how statistics are used, reported, and manipulated. Examples and demonstrations of real-life applications are included to enable the reader to think carefully about the statistics that confront us daily - in our newspapers, in the classroom, and in the claims of politicians and advertisers.
