normal distribution

statistics (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.
