- Scree plot
- Use a scree plot to identify the number of factors that explain most of the variation in the data.
- Score plot for first 2 factors
- Use the score plot to look for clusters, trends, and outliers for the first two factors.
Note
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 to display them.
- Loading plot for first 2 factors
- Use the loading plot to visually interpret the first two factors.
Note
To create simple loading plots for other factors, store the loadings and use to display them. If you want to connect the loading point to the zero point, add a zero to the bottom of each column of loadings in the worksheet, then add lines connecting the loading points to the zero point using the graph annotation tools.
- 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.
