Lecture 6: Psychometric instrument development
This lecture recaps the previous lecture on exploratory factor analysis, and introduces psychometrics and (fuzzy) concepts and their measurement, including (operationalisation), reliability (particularly internal consistency of multi-item measures), validity and the creation of composite scores.
This lecture is accompanied by a computer-lab based tutorial.
