A co-worker asks the following:

   Someone did the following survey:
     - Population = 600
     - Surveyed   = 600   (ie. non-random)
     - Question posed is binary: happy - yes or no
     - Return: 225 answered, 80% yes, 20% no

   One should be able to calculate the deviation on a random survey. How
   about a non-random one with a serious non-response bias like the above
   example? What deviation should be used? Can it be calculated? These
   kinds of surveys are common in the corporate world but I always raise
   the issue of it being non-random and having serious non-response. Now
   I'd like some expert feedback and some numbers.
