title: How to calculate the statistics "t-test" with numpy
body: <p>I'm looking to generate some statistics about a model I created in python.  I'd like to generate the t-test on it, but was wondering if there was an easy way to do this with numpy/scipy.  Are there any good explanations around?</p>
  
  <p>For example, I have three related datasets that look like this: </p>
  
  <pre><code>[55.0, 55.0, 47.0, 47.0, 55.0, 55.0, 55.0, 63.0]
  </code></pre>
  
  <p>Now, I would like to do the student's t-test on them.</p>
