normal distribution
     
         (Or "Gaussian distribution", "bell curve") The
        {frequency distribution} of many natural phenomena such as the
        height 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}.
