  1. On the Clustering dialog box, click on RESULTS.
  2. Click sizes graph.
    Clustering > Results > Sizes Graph

    The Sizes (and Distances) graph plots the mean values of a pair of variables at a time, indicating the clusters by color and number label, and the standard deviations (square root of the variance) by the size of the ellipse surrounding the mean point, using the same color-coding. Roughly speaking, this graph depicts the separation of the clusters with respect to pairs of model variables. The following options are available:
    • Non-Normalized — The default value to show the clusters without any normalization.
    • Normalized — With the Normalized option, cluster means are divided by the largest absolute mean and the size of the circle based on the variance is divided by the largest absolute variance.
    • Variables
      • Available — The variables that were input into the Clustering analysis.
      • Selected — The variables that are shown on the Size and Distances graph. Two variables are required to be entered here.
    • Clusters
      • Available — A list of clusters generated in the clustering solution.
      • Selected — The clusters that are shown on the Size and Distances graph. Up to twelve clusters can be selected to be shown on the Size and Distances graph.
    • Zoom In — While holding down the left mouse button on the Size and Distances graph, drag a lasso around the area that you desire to magnify. Release the mouse button for the zoom to take place. This can be repeated until the desired level of magnification is achieved.
    • Zoom Out — Press the Z key, or toggle the Graph Options tab to go back to the original magnification level.
