Introduction to digital trace data: Quality, ethics, and analysis

Introduction to Digital Trace Data gives students a hands-on introduction to digital behavioral data: how it’s collected, analyzed, and interpreted. The course explores different types of data and research methods, while also encouraging students to think critically about how data and algorithms can shape, and sometimes reinforce, social inequalities.
