## Introduction to This Page

This page is meant to supplement the syllabus and lectures for my undergraduate course "Introduction to International Relations" (PSCI 3300) at the University of North Texas. It is organized along the same outline as the reading list for the course, to help students who wish to go beyond the original assigned readings.

Obviously, this page -- like any other page on the Web -- is a work in progress. I will do my best to keep it up-to-date throughout the semester. Unfortunately, many of these links may be redirected or even removed from the Web by the end of the semester (one semester I found that over one-third of all of the links on one of my pages broke between September and December). I would appreciate being informed via email if you find any broken links on this page, so that I can attempt to fix or delete the link in question.

## Using SPSS (and PSPP) Software

SPSS statistical software ("Statistical Package for the Social Sciences") is used in many academic settings and many businesses, so experience using it can be very helpful after completing this course. Even if you end up in a discipline or business that uses a different statistical package, the experience of having worked with SPSS will help you make the transition to their preferred software much more easily than if you had never done this. This document offers a brief introduction to SPSS and guidelines on how to use it for this course's homework assignments. Note that this will be a work in progress, with more guidelines and instructions being added later in the semester as later assignments require additional statistical techniques, and I will eventually add material that won't be required this semester but could be very helpful if you ever use SPSS for future research, coursework, or employment (such as reading in raw data, formatting and recoding data, and using SPSS syntax files rather than just using the dropdown menus).

These additional online resources go into more detail about some of the techniques and options that we will be using in this course's homeworks, as well as many of the techniques and options available in SPSS that we will not be using this semester but that you might need to use later:

- SPSS Manuals (more detail on what each command does and what options are available)
- Online SPSS Tutorials:
- Philip H. Pollock III (2015), IBM SPSS Companion to Political Analysis, 5th edition. (A book about using SPSS that is intended as a companion to the textbook)

** Using PSPP**: These resources cover the use of PSPP, the free open-source equivalent to SPSS. Based on my testing so far, it should work almost identically to SPSS, except that PSPP does not currently offer some of the more advanced statistical techniques that we will discuss at the end of the semester (although it does everything that is required for course homework assignments).

- PSPP Manual (more detail on what each command does and what options are available)
- PSPP FAQs
- Online PSPP Tutorials:
- Basic Stats in PSPP (from Norm Lewis of the University of Florida)
- PSPP Tutorial (from NC State University)

## Methodology References

While many students in this course will be satisfied with completing the course and will not want to use quantitative methods in their own careers (at UNT or afterward), others will want to go further with topics covered in this course, perhaps in writing a senior honors thesis or in preparing for graduate school. This is not a definitive list, but these resources might be helpful guides for going further with these methods than we could in this class. Many of these are from Sage Publications' *Quantitative Applications in the Social Sciences* series, which offers relatively brief (around 80 pages), accessible, and affordable (around $20) discussion of many important topics (these volumes are often consulted by grad students and faculty doing their own research).

*Empirical Political Analysis*, various editions. Routledge/Taylor and Francis. (A book that a number of my colleagues have used over the years. This book does a good job of covering a lot of material, but it is also quite pricey, at nearly three times the cost of the Pollock book.) - Janet Buttolph Johnson, H.T. Reynolds, and Jason D. Mycoff.
*Political Science Research Methods*, various editions. Sage/CQ Press. (I have used this book in the past. This does a good job of covering the material used in this course, and adds far more coverage of various data sources and data collection techniques than we have time for in the course as I currently teach it; a bit pricier than the Pollock book) - Paul M. Kellstedt, Guy D. Whitten, and Steven A. Tuch
*The Fundamentals of Social Research*, various editions. (The book that I am currently using for this course - some of the chapters are a little more advanced than in some of the other books, but overall better coverage of more topics than any of its competitors, and currently the lowest price.)
