NORMDIST

Calculates values for a normal distribution.

Syntax:

NORMDIST(x; μ; σ; mode)

The normal distribution is an often encountered family of continuous probability distributions, with parameters μ (mean) and σ (standard deviation).

If mode is 0, NORMDIST calculates the probability density function of the normal distribution:

If mode is 1, NORMDIST calculates the cumulative distribution function of the normal distribution:

Example:

NORMDIST(70; 63; 5; 0)

returns approximately 0.03.

NORMDIST(70; 63; 5; 1)

returns approximately 0.92.
