Related to what I am using to estimate the mean, it is not the component from factor analysis, but the factor scores I obtained from SPSS (see attachment 1). When you perform a factor analysis in SPSS, the software gives you the option of saving the factor scores as a variable (see attachment 2). As a result, I obtained a new variable in my dataset with 2457 observation, the exact number of observation that I have for the original values. I estimated the mean of this values.
