NORM.S.DIST

## Category:

Statistical Analysis

## Summary:

Calculates values of the probability density function or cumulative distribution function for the standard normal distribution. The standard normal distribution has a mean of zero and a standard deviation of one.

## Syntax:

NORM.S.DIST(Number; Cumulative)

## Returns:

Returns a real number in the range [0, 1] which is the value of the probability density function or cumulative distribution function for the standard normal distribution for the specified value.

## Arguments:

Number is a real number or a reference to the cell containing that number which is the value for which the standard normal distribution is to be calculated.

Cumulative can be 0 or False to calculate the probability density function. It can be any other value or True to calculate the cumulative distribution function.

## Additional details:

• The formula for NORM.S.DIST is:

If Cumulative is FALSE(), NORM.S.DIST returns the probability density function value

If Cumulative is TRUE(), NORM.S.DIST returns the cumulative distribution function value
