title: How to calculate mean and standard deviation for hue values from 0 to 360?
body: <p>Suppose 5 samples of hue are taken using a simple HSV model for color, having values 355, 5, 5, 5, 5, all a hue of red and "next" to each other as far as perception is concerned.  But the simple average is 75 which is far away from 0 or 360, close to a yellow-green.</p>
  
  <p>What is a better way to calculate this mean and associated std?</p>
