How to correlate an Ordinal Categorical column in pandas?

Question

I have a DataFrame df with a non-numerical column CatColumn.

   A         B         CatColumn
0  381.1396  7.343921  Medium
1  481.3268         


        

Answer 1

Basically, there is no a good scientifical way to do it. I would use the following approach: 1. Split the numeric field into n groups, where n = number of groups of the categorical field. 2. Calculate Cramer correlation between the 2 categorical fields.
