A variety of digital data sources are providing new avenues for empirical social science research. To effectively utilize these data for answering substantive research questions, a modern methodological toolkit paired with a critical perspective on data quality is needed. Organized and offered in collaboration with BERD@NFDI, this course introduces state-of-the-art data science techniques that are suited for collecting and analyzing digital behavioral data, so-called "big data", and traditional survey data. In addition, aspects of data quality and error frameworks for digital (big) data sources are discussed.

Course leader

Christoph Kern is a Post-Doctoral Researcher at the Universities of Mannheim, Germany, and Maryland, USA. Malte Schierholz is a Post-Doctoral Researcher at Ludwig-Maximilians-Universit√§t M√ľnchen, Germany.
