A factor-based score, on the other hand, is merely a linear composite of the variables that demonstrate meaningful loadings for the component in question. In the preceding analysis, for example, items 4, 5, and 6 demonstrated meaningful loadings for the “financial giving” component. Therefore, you could calculate the factor-based score on this component for a given participant by simply adding together her responses to items 4, 5, and 6. Notice that, with a factor-based score, the observed variables are not multiplied by optimal weights before they are summed.
O’Rourke, Norm, and Larry Hatcher. A Step-by-Step Approach to Using SAS® for Factor Analysis and Structural Equation Modeling, Second Edition. , Cary, North Carolina, USA. ALL RIGHTS RESERVED. com/bookstore. 1 provides simple statistics for the observed variables included in the analysis. Once the SAS log has been checked to verify that no errors were made in the analysis, these simple statistics should be reviewed to determine how many usable observations were included in the analysis, and to verify that the means and standard deviations are in the expected range.

Both have means of 0 and standard deviations of 1; these variables were constructed to be standardized variables. The correlations between FACTOR1 and FACTOR2 and the original observed variables appear at the bottom half of page 5.
