In this seminar, you will learn to understand, apply, and interpret linear models based on the ideas of regression. It will be explained, what assumptions underly these type of models, how they can be computed in analysis software (like R or SPSS), and how they should be interpreted. Depending on the pace of the participants, you will learn first to calculate and interpret various kinds of mediation and moderation models. This might later be extended to hierachical linear (multilevel) and logistic models. Having a problem to analyze like a thesis at hand is welcomed, but not a precondition to the course.
