title: Is there a way to get correlation with string data and a numerical value in pandas?
body: <p>I'm trying to get a correlation in pandas that's giving me a bit of difficulty. Essentially I want to answer the following question: given a sentence and a value and a dataframe, what word correlates the best with a higher value? What about the worst?</p>
  
  <p>Trivial example:</p>
  
  <pre><code>Sentence      | Score
  "hello there" | 100
  "hello kid"   | 95
  "there kid"   | 5
  </code></pre>
  
  <p>I'm expecting to see a high correlation value here for the word "hello" and score.  Hopefully this makes sense -- if this is possible natively in Pandas I'd really appreciate knowing!</p>
  
  <p>If anything is unclear please let me know.</p>
