A Stata® Companion to Political Analysis

Fourth Edition

October 2018 | 288 pages | CQ Press

“This textbook is a great resource for teaching students how to conduct basic quantitative analysis using Stata. It provides intuitive examples from real data sets. I think it is a great resource for teaching students how to carry their own research projects.”
—Sabri Ciftci, Kansas State University

Popular for its speed, flexibility, and attractive graphics, Stata is a powerful tool for political science students. With Philip Pollock's Fourth Edition of A Stata® Companion to Political Analysis, students quickly learn Stata via step-by-step instruction, more than 50 exercises, customized datasets, annotated screen shots, boxes that highlight Stata's special capabilities, and guidance on using Stata to read raw data. This attractive and value-priced workbook, an ideal complement to Pollock’s Essentials of Political Analysis, is a must-have for any political science student working with Stata.

“An excellent companion for statistical computing using Stata that is a must-use for those instructors that assign the Pollock text and use Stata in their course."

Donald Gooch

“This textbook is a great resource for teaching students how to conduct basic quantitative analysis using Stata. It provides intuitive examples from real data sets. I think it is a great resource for teaching students how to carry their own research projects.”

Sabri Ciftci
Kansas State University

“This is a great workbook to teach Stata to students who are also learning the basics of statistical analysis. It comes with four datasets that can be used to run analyses. Its exercises are very useful and the instructor tools are great.”

Tijen Demirel-Pegg
Indiana University – Purdue University Indianapolis

“For teaching Stata to undergraduates, this book provides the friendliest approach I have found. Over six straight semesters of teaching the same course, I have found it to make both my teaching experience and the students’ learning experience far more interesting and interactive than a typical “Research Methods” course. It provides exceptional instructional assistance, and presents information to students in an easily digestible way.”
