Block C – Designing and Running Experiments

Block C walks you through the basic methodology of experimental research and also teaches you how to use an online tool to develop and run your experiments. The block lasts 4 days and is worth 2 ECTS.

Firstly, we will discuss basic principles of experiments and experimental games.

Second day is dedicated to internal and external validity of experiments, i.e. the certainity that the tested relationship is not influenced by unknown variables and the extent to which those findings can be applied to other situations.

On the third day we will take you through the process of pre-registration and show you how to write instructions for participants.

And on the last day of the block we will dive into working with Lioness Lab, a free web-based platform for interactive online experiments.
