New research is the most exciting and important aspect of political science: we are able to pose novel questions, construct fresh theories, and provide new evidence about the way the world works. But before we start doing research, we have to learn how it is done. With this in mind, this class will introduce students to quantitative techniques used for research in the study of politics. Part of this task is conceptual: helping students to think sensibly and systematically about research design. To this end, students will learn how data and theory fit together, and how to measure the quantities we care about. But part of the task is practical too: students will learn a `toolbox' of methods--including statistical software--that enable them to execute their plans.
