The Cluster Members report shows that there are four variables in Cluster 1. In the Color Map on Correlations, the four-by-four square of cells in the upper left corner that corresponds to these five variables shows a distinct pattern of positive correlations. The color map also shows patterns of positive correlations for the variables in Clusters 2, 4, and 5. The two-by-two square of cells in the lower right corner of the color map that corresponds to the two Cluster 6 variables shows that they are negatively correlated. For more details, see Color Map on Correlations.
