In this  workshop, we will discuss the logic of experimentation, its strengths  and weaknesses compared to other methodologies, and the ways in which  experimentation has been -- and could be -- used to investigate  political, social, and economic phenomena.  Emphasis will be placed on  field experiments, randomized trials conducted in real-world settings.   Examples will be drawn from a broad array of disciplines.


After  describing the attractive statistical properties of experiments, we  consider a variety of potential threats to core assumptions.  In  particular, we consider the complications that arise when (1) treatment  and control conditions different in systematic ways other than the  intended treatment, (2) treatments are not administered according to the  randomly assigned plan, (3) subjects are affected by the treatments  assigned or administered to others, and (4) outcome measures are not  obtained for all subjects.  In each case, we discuss possible  statistical and design solutions.  We conclude by discussing the  practical and ethical issues that arise when conducting experiments in  field settings.

Audience & Prerequisites

This  workshop serves as a broad introduction to social science experiments.  Participants are expected to come to the session with some experience  designing a research study and with a question or hypothesis that they  wish to investigate using experimental design.

Readings & Resources

The primary text for the course is

Gerber, Alan S., and Donald P. Green.  2012.  Field Experiments: Design, Analysis, and Interpretation.  New York: W.W. Norton.


This  textbook (FEDAI for short) is too extensive to be covered in two  sessions, but we will make our way through much of the first half, which  covers core topics.

Supplementary  readings are designed to illustrate a wide range of experimental  applications.  They will be provided to participants via a shared  Dropbox folder.  Further readings beyond the dropbox PDFs are available  on request.

Data  analysis examples will be provided in both R and Stata format, but no  special programming expertise is required.  If you have some experience  with statistical software, you can join in when we analyze data  together.
