Gaussian distribution

    (Or "Gaussian distribution") The frequency
   distribution of many natural phenomena such as the height or
   intelligence of people of a certain age and sex.  The formula
   looks something like:

   	P(x) = e^(((x-m)/s)^2)

   where P(x) is the probability of a measurement x, m is the
   mean value of x and s is the standard deviation.

   Also known as a "bell curve" because of its shape.
