• SQUARES are categorical associations (uncertainty coefficient & correlation ratio) from 0 to 1. The uncertainty coefficient is assymmetrical, (approximating how much the elements on the left PROVIDE INFORMATION on elements in the row).
• CIRCLES are numerical correlations (Pearson's) from -1 to 1.
• The trivial DIAGONAL is intentionally left blank for clarity.
