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

f(x) = 1/[2*)1/2*] * e**{-1/2*[(x-µ)/]2}
- < x <

where
 µ     is the mean
   is the standard deviation
 e     is the base of the natural logarithm, sometimes called Euler's e (2.71...)
   is the constant Pi (3.14...)
