From Correlation Matrices to Factor Models



Notes: T1 through T4 of this (fictitious) example represent mental tasks administered to 1000 participants on four mental ability tasks. The correlations among them are shown in the left-most tables of the columns. In the middle column, the roman numerals designate the first and second factors extracted for the one- and two-factor cases illustrated in the two rows. The numbers beneath them represent the estimated correlations between the four individual tasks and the factor(s); those correlations are referred to as factor loadings. The final column represents a diagrammatic depiction of the results, although a full depiction would include the factor loadings next to each connecting line. More details: The three correlation matrices were factor analyzed using R. The exploratory solutions (top rows) were conducted with the PSYCH package using a principal axis extraction followed by a varimax rotation, for the two-factor case. The extraction was checked in SPSS. The bottom, hierarchical CFA was conducted in Lavaan using a Maximum Likelihood extraction. Fit statistics were 1.0 for both the CFI and TLI and 0 for the RMSEA.

The following is an ancillary analysis of the open-source data from Bryan & Mayer, 2020 that illustrates how each of ten broad intelligences loads on a general intelligence factor (g).
