The course will provide an overview of a variety of experimental techniques that have been implemented in survey research recently. We will start with the idea and principles of experimentation in the social sciences. The participants will obtain profound knowledge about the criteria that guide decisions for experimental techniques. The distinctive feature of experiments consists in the possibility to study causal relationships by manipulating the 'causes' in order to analyse their "effects" upon the "outcomes". The course will cover a selection of the most important experimental techniques in survey research, i.e. split-sample experiments, randomised response techniques, group work and practical exercises. However, the format of the course is interactive, thereby relying upon the participants' active contributions.
