Two kinds of coefficients can describe the correlation between two columns:
Each correlation coefficient can take values between -1 and 1. To view the correlation coefficient between two numeric columns:
If the column in the covariate table is a category column, the rank correlation will be displayed; otherwise, the product-moment correlation will appear. Each correlation coefficient will appear in black if it is statistically significant at the current confidence level; if it is not statistically significant, it will appear in gray.
