Score plot for first 2 factors
Use the score plot to look for clusters, trends, and outliers for the first two factors.
Scores must be calculated from raw data. Therefore, you cannot display this plot if you select Use matrix on the Options subdialog box. To create score plots for other factors, store the scores and choose Graph > Scatterplot to display them.
Loading plot for first 2 factors
Use the loading plot to visually interpret the first two factors.
Biplot for first 2 factors
Use the biplot to look for clusters, trends, and outliers through the interpretation of the first two factors. The biplot overlays the score plot and the loading plot on the same graph.
