How can we tell whether providing child care will encourage more welfare recipients to work? How do we know whether tougher drunk-driving laws will reduce accidents? This course explains how social scientists try to determine the truth about public issues. Topics covered include descriptive statistics, sampling distributions, hypothesis testing and regression, with a focus on how those tools are used in public policy debates. Mathematical formulae are kept to a minimum, and the intuition behind statistical procedures is emphasized.
