GAUSS Function

Excel 2013+

Summary

The GAUSS function calculates the probability that a value from a standard normal distribution falls between the population mean (zero) and a specified number of standard deviations (z). This is useful for statistical analysis and quality control applications.

Syntax

GAUSS(z)

Parameters

Parameter Type Required Description
z Number Yes The z-score representing standard deviations from the mean in a standard normal distribution

Using the GAUSS Function

GAUSS is primarily used in statistical analysis to determine probabilities in standard normal distributions. It returns the area under the standard normal curve from the mean to the z-value, which represents cumulative probability up to that point minus 0.5.

Common GAUSS Examples

Basic GAUSS Calculation

=GAUSS(2)

Returns 0.47725, the probability that a standard normal variable falls between 0 and 2 standard deviations (about 47.7% of the distribution)

Negative Z-Score

=GAUSS(-1.5)

Returns approximately 0.4332, probability between mean and -1.5 standard deviations

Z-Score from Cell

=GAUSS(A1)

Where A1 contains 0.5, returns approximately 0.1915

Frequently Asked Questions

GAUSS(z) = NORM.S.DIST(z,TRUE) - 0.5. GAUSS gives the tail probability from mean to z, while NORM.S.DIST gives cumulative probability from negative infinity.

Yes, negative z values return the probability in the left tail of the distribution.

GAUSS(0) returns 0 since there's no area between the mean and itself.

Common Errors and Solutions

#NUM!

Cause: z argument is not a valid number

Solution: Ensure z contains numeric data only

#VALUE!

Cause: z argument is not a valid data type

Solution: Check that z is a number, not text or error value

Notes

  • GAUSS(z) is always NORM.S.DIST(z,TRUE) - 0.5
  • For z ≤ 0, returns 0 (no area between mean and z)
  • Symmetric: GAUSS(-z) gives left tail probability
  • Excel 2013+ only - use NORMSDIST in older versions
