Three different methods were presented for the computation of scale scores: summing raw scores on the X variables, summing z scores on the X variables, and saving factor scores from a FA of a set of X variables. (Assume that all the X variables are measures of a single latent construct.) How are the scores that are obtained using these three different methods of computation typically related?
