In Philip H. Pollock's An IBM SPSS® Companion to Political Analysis, 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 fresh guided examples, new annotated screenshots, step-by-step instructions, and exercises that reflect current scholarly debates in American political behavior and comparative politics. Compatible with all releases of SPSS (12.0 and later), the all-new Fifth Edition includes 53 new or revised exercises. Two new datasets (NES 2012 and GSS 2012) and two revised datasets (on the 50 states and on 167 countries of the world) feature an expanded number of variables to provide greater latitude for performing original analysis.
