title: How to correlate an Ordinal Categorical column in pandas?
body: <p>I have a DataFrame <code>df</code> with a non-numerical column <code>CatColumn</code>.</p>
  
  <pre><code>   A         B         CatColumn
  0  381.1396  7.343921  Medium
  1  481.3268  6.786945  Medium
  2  263.3766  7.628746  High
  3  177.2400  5.225647  Medium-High
  </code></pre>
  
  <p>I want to include <code>CatColumn</code> in the correlation analysis with other columns in the Dataframe. I tried <code>DataFrame.corr</code> but it does not include columns with nominal values in the correlation analysis.</p>
