In this much-anticipated revision of the popular SPSS workbook, students dive headfirst into actual political data and work with a software tool that prepares them for future political-science research. Students learn by doing with guided examples, more than 120 screenshots, and step-bystep instructions. Compatible with all releases of SPSS (12.0 through 19.0, as well as the student version), the new Fourth Edition includes brand-new or completely revised exercises. Two new data sets (2008 NES and 2008 GSS) and two revised data sets (on the 50 states and on 191 countries of the world) feature an expanded number of variables to provide greater latitude for performing original analysis.
