Document Summary
Fa - to reveal patterns and relationships among a large number of intercorrelated measures. It only shows that we can account for the intercorrelations and link it to some underlying factor. The factors that emerge depend on what the intercorrelated measures are. It doesn"t identify what those underlying things are. All it does is identify the scores whose values seem to go together and that it might be related to that underlying something. They can be cognitive patterns or underlying unconscious factors. There"s no single factor-analytic solution to any particular intercorrelated scores. You can perform a factor analysis so that whatever you get is orthogonal - uncorrelated. Depends on the data you out into it. Exploratory fa - used to reduce data to a smaller set of summary variables to explore the underlying structure. Confirmatory fa - is to verify the structure of a set of observed variables.
