This course is designed to teach the logic and method of data analysis. We start with a specified research question, find some data that are pertinent to this question, and analyze them. The analysis proceeds first by studying the univariate statistical distributions of relevant variables, then moves on to bivariate and multivariate methods. Students write about their research question; emphasis is placed on the interaction between the results of data analysis and the revision of the research question. Note: This is a research-intensive course.
