title: MS Access 2010 Report Group average
body: <p>I have grouped my data like this:</p>
  
  <pre><code>   Student
        Class Type
             Class Date
  </code></pre>
  
  <p>Under class date, I have Date, Test Score, and Class Average columns.</p>
  
  <p>How can I get the class average for a given date?
  Thanks</p>
