A normal frequency distribution is a continuous, symmetrical, bell-shaped distribution function. Its mean, mode and median are all the same; and both the tails of the bell curve are infinitely long.

Because of its symmetry, a normal frequency distribution can be described fully by its mean and its standard deviation.

Commonly abbreviated to normal distribution.
