# GAUSS function

This article describes the formula syntax and usage of the GAUSS  function 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

Copy the example data in the following table, and paste it in cell A1 of a new Excel worksheet. For formulas to show results, select them, press F2, and then press Enter. If you need to, you can adjust the column widths to see all the data.
