Designing and Conducting Experiments Rick K. Wilson Department of Political Science Rice University Catherine C. Eckel Economics Texas A&M University Course Objective: This course develops the role of experimental methods in the social sciences. Experiments are one of the tools available for research in the social sciences, one that plays an increasingly prominent role in economics and political science. There are three goals for the course. First is to illustrate the connection between theory and experimental design in both directions: the use of experimental designs to test theories directly in the lab, and the impact of experimental results on the development of theory. Second, we will discuss the elements of experimental design, and what makes a good experimental study: the simplest design is often the best. Finally, we want to provide a sense of the kinds of problems – in design, implementation, and data analysis – facing various types of experiments (from lab experiments, to lab-in-the-field experiments, to field tests and randomized control trials). To learn about experiments, there is no substitute for hands-on experience, so participants will work individually or in groups of up to size four to design an experiment that will be presented in the workshop. On the last day of class students will present their experimental designs, with feedback from the instructors and other students, and time permitting some groups may be able to conduct a pilot of their design.
