title: Analyze multiple response field from google doc form
body: <p>One of my questionnary made with Google Doc have a multi response set.</p>
  
  <p>Let's say the three possible questions are :</p>
  
  <ul>
  <li>foo </li>
  <li>bar </li>
  <li>foobar</li>
  </ul>
  
  <p>People where allowed to tick one or more answers.</p>
  
  <p>In my google spreadsheet results, I have :</p>
  
  <pre><code>answer1 : foo
  answer2 : foo, bar
  answer3 : bar, foobar
  answer4 : foo, foobar
  anwser5 : foobar
  etc.
  </code></pre>
  
  <p>How could I analyze this type of result in SPSS ?</p>
  
  <p>I have the intuition that the values could be split in multiple answers to multiple questions by I don't know how to do this.</p>
  
  <p>Thanks</p>
