In this Fifth Edition of their best-selling Social Statistics for a Diverse Society, Chava Frankfort-Nachmias and Anna Leon-Guerrero use straightforward, conversational prose and emphasize common sense as they demonstrate the link between the practice of statistics and important social issues. The book helps students learn key sociological concepts through real research examples related to the dynamic relationship between race, class, gender, and other social variables. An emphasis on SPSS (version 16.0) throughout the book, in conjunction with General Social Survey data, introduces students to one of the most commonly used analytical software packages. Each chapter ends with a demonstration of a related SPSS procedure, along with a set of useful exercises to help students practice what they learn.
