Normal Distribution

The normal distribution (the term first used by Galton, 1889) function is determined by the following formula:

f(x) = 1/[(2p)1/2 * s] * e**{-1/2*[(x-m)/s]2}

∞ < x < ∞

where

m

is the mean

s

is the standard deviation

e

is the base of the natural logarithm, sometimes called Euler's e (2.71...)

p

is the constant Pi (3.14...)
