<p>I have noticed that on a previous year's AP Free Response Section, one of the questions required the test-taker to apply the Chi Square Test to ratios of a punnet square. I am confused. Why would AP Bio have this as a section on the exam?</p>
<p>Really? I thought that was Stats... Hmm... must be used in Bio too.</p>
<p>:)</p>
<p>Chi square tests are part of the ap bio curriculum. If you get the official lab manual from collegeboard it's even covered in it.</p>
<p>It's part of the mutation lab, if I recall correctly.</p>
<p>It was the essay question for 2003.</p>
