[AISWorld] MTMM and Mk I eyeball

[Cecil Eng Huang Chua]

Hi all,

I was wondering if someone had a correlation matrix that was easy to analyse for introductory students with the Mark I eyeball.  Basically, what I want is a set of constructs with arrows, and the accompanying correlation matrix.  I want to be able to show that good fit is just simply high correlation within factor, low correlation across unrelated factors, and that full mediation A->B->C means Corr(A,B)*Corr(B,C) is similar to Corr(A,C).  And that the direction of correlations should generally "flow."

Yes, I can cook up the data.  I already do.  What's better for an exercise is if this was a published study with published statistical results.  The matrix has to be clean enough to see with the Mk I eyeball, however.  Or, the dirt has to be so obvious we can say, "When you run your CFA, this is going to be the problem."  So, my trawling through published work looking at correlation matrices is not going to be useful, given most research numbers aren't very clean.

The context is I am teaching a research methods class.  The class focuses on the literature review and methodological components of empirical research.  The class emphasis is that tools are nothing more than an extension of the mind.  For example, in the statistics component, I emphasize how statistics are the LAST thing you do, not the first.   Before the stats is the proper study design.
