The interest in methods is at the heart of our research endeavours. Beside the application of quantitative and qualitative methods in research projects, we gather expertise in three areas: First, we are interested issues of methodological theory, such as the causal logic of experimental data, or issues of operationalization and validity. Second, our staff applies basic and sophisticated statistical methods in our studies and projects. Third and last, methods play a crucial role in teaching. We offer courses in descriptive & inferential statistics, multivariate analysis, and logic of research design.
