    10. Submit Reflection and feedback for unit 7

    The unit continues from the previous unit by introducing confirmatory factor analysis (CFA), structural regression models, and some of their post-estimation tools. In the seminar, we discuss also conceptualization and scale development processes. After this unit, you should:

    • Understand the difference between exploratory and confirmatory factor analysis.
    • Have a basic understanding of the workflow for a confirmatory factor analysis.
    • Know what the chi2 statistic in a CFA tests, know why it is the most important statistics that the analysis provides, and have a basic understanding of what to do when the chi2 test rejects the model (which it often does).
    • Know the basic idea of structural regression models. (This analysis technique is a bit more advanced and it is not addressed on the course in detail, but it is useful to know the basic idea because the technique is widely used.)
    • Know why the idea of "formative measurement" is problematic.
    • Know when and why indices constructed from non-scale variables can be useful and how such indices can be justified.
    • Understand the importance of conceptualization as a first step in measurement development and have a basic understanding of a commonly used scale development procedure. (This is not covered in the videos, but will be discussed in the seminar.)
