Correlation Methods Correlation and Covariance Matrices Fisher's z Transformation ( z r ) Pearson Product-Moment Correlation Coefficient (Pearson's r ) Spearman's Rank-Order Correlation Coefficient (Spearman's ρ) Kendall's Rank Correlation Coefficient (Kendall's τ) Correlation and Covariance Matrices You can generate a correlation or covariance matrix from numeric data columns, and have the choice of storing the computation results in an-autogenerated worksheet, or display the results in a table format whose values can be color coded. This method requires multiple numeric data columns whose values should be stored in a single worksheet. An example of a correlation matrix displayed as a color-coded table is shown below. Using Fisher's z Transformation ( z r ) This option is provided to allow transforming a skewed sampling distribution into a normalized format. The theoretical sampling distribution of the corr...
