I have served as TA, leading two precepts each, for the following political methodology courses:
Introduction to Quantitative Social Science (Princeton University)
POL345 : The course introduces basic principles of statistical inference and programming skills for data analysis. The goal is to provide students with the foundation necessary to analyze data in their own research and to become critical consumers of statistical claims made in the news media, in policy reports, and in academic research.
Political Analysis (University of California, San Diego)
POLI30 : Introduction to the logic of inference in social science and to quantitative analysis in political science and public policy including research design, data collection, data description and computer graphics, and the logic of statistical inference (including linear regression).
