      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.
