Spearman Correlation Tool

Last modified: May 13, 2020

Use the Spearman Correlation tool to assess how well an arbitrary monotonic function can describe the relationship between two variables, without making any other assumptions about the particular nature of the relationship between the variables. Correlation coefficient values range from –1.00 (a perfect negative correlation) to +1.00 (a perfect positive correlation). Zero indicates no correlation at all.

Configure the Tool

Field Selection Tab

Choose the two fields (columns) to determine the Correlation. The two fields must be numeric and the same field cannot be chosen twice. Columns that contain unique identifiers, such as surrogate primary keys and natural primary keys, should not be used in statistical analyses. They have no predictive value and can cause runtime exceptions.

Group By (Optional) Tab

To determine the correlation for a group, select Enable Group By and select the appropriate grouping field (column).

Description Tab

The Description tab contains this description:

Spearman's rank correlation coefficient assesses how well an arbitrary monotonic function could describe the relationship between two variables, without making any other assumptions about the particular nature of the relationship between the variables.
