Researchers and practitioners often operationalise a whole range of concepts and aim to measure these. Different research techniques are used such as surveys, tests, observation schemes. After this course one has the basic knowledge to judge the quality of existing measurement instruments and to develop research instruments by oneself.
The focus in this course is put on the scientific criteria that are used to develop research instruments: validity and reliability. A broad framework is introduced enabling critical reflection regarding the reliability and validity of instruments and critical analysis of results. A number of statistical analyses are taught using the research package R, in order to test the quality of operationalisation.
