Data and data analysis are increasingly important for political science research, but also in the public discourse and the workplace. In this class, you will learn how to conduct data analysis yourself. We'll cover topics such as finding data, data cleaning and data manipulation, data visualization, and data analysis. Along the way, we'll learn basic statistical functions and plots in the powerful (and free) statistical program R. Throughout, the class takes an applied approach, so students will develop their own research project and conduct their own data analyses.
Kosuke Imai (2017): Quantitative Social Science: An Introduction. Princeton University Press.
I will refer to the book as QSS. You can rent/buy the book from Amazon, Princeton University Press, or your favorite book retailer as hardcover, paperback, or e-book. The book should also shortly be available to check out for a short period of time from the Library Course Reserves. I will post copies of the assigned chapters for the first week or two to give everyone a chance to get access to the book.
ASSIGNMENTS AND GRADING
- Class Participation (15%): To succeed in this course, you have to attend class on a regular basis, come prepared by having worked through the assigned reading, and actively participate and ask questions.
- Class Programming Review Exercises (10%): There will be short weekly review exercises that cover the basic R material we learned. Each exercise is graded as pass/fail, where a pass is worth 1 point and a fail worth 0.
- Problem Sets (30%): There will be 5 to 6 problem sets in which you are asked to use what you have learned in class to analyze different kinds of data. The answers to these problem sets should be typed. They are graded on a scale from 1 to 5, and late submissions will be penalized by 1 point for every 24 hours past the due date. Any extension requests must be made to me personally and as soon as possible.
- Data Analysis Memos (15%): Your main task in this class will be to write a paper with your own data analysis on a question that is of interest to you. To help you along the way, you will submit reports about the individual steps throughout the semester. The memos will cover: your research question and potential confounders, your data, data cleaning, descriptive statistics, bivariate relations, (first) regression results. The memos should be short (2-3 pages) and typed in their entirety. They are graded on a scale from 1 to 5, and late submissions will be penalized by 1 point for every 24 hours past the due date. Any extension requests must be made to me personally and as soon as possible. I will provide feedback to every memo to help you improve your final paper.
- Data Analysis Paper (30%): Your final paper should set out your research question, explain the data and statistical methods you use to investigate it, and describe what, based on your data analysis, the answer is. There is no minimum or maximum paper length. It should be as long as needed, but as short as possible. The papers are due at the beginning of the finals period (May 18).
For more detailed information on class policies and all of the fine print, please see the Syllabus.
