# GAUSS function

This article describes the formula syntax and usage of the GAUSS function (function: A prewritten formula that takes a value or values, performs an operation, and returns a value or values. Use functions to simplify and shorten formulas on a worksheet, especially those that perform lengthy or complex calculations.) in Microsoft Excel.

## Description

Calculates the probability that a member of a standard normal population will fall between the mean and z standard deviations from the mean.

## Syntax

`GAUSS(z)`

The GAUSS function syntax has the following arguments.

• Z    Required. Returns a number.

## Remarks

• If z is not a valid number, GAUSS returns the #NUM! error value.
• If z is not a valid data type, GAUSS returns the #VALUE! error value.
• Because NORM.S.DIST(0,True) always returns 0.5, GAUSS (z) will always be 0.5 less than NORM.S.DIST(z,True).

## Example

The workbook below shows examples of this function. Inspect them, change existing formulas, or enter your own formulas to learn how the function works.
