In the first part (first five lectures) of Module 3, I talk about the concept of reliability, why is reliability computed and its use in research in social sciences. n the second part (lecture 6 onwards) of this module, I explain the theory of factor analyses (EFA - exploratory factor analysis and CFA - confirmatory factor analysis).
Module covers aspects of reflective and formative constructs. Also, I would be talking about the steps to be followed while developing items for scales used in social science research.
