# GAUSS

Formulas / GAUSS
Calculate the probability of a standard normal population member falling between the mean and standard deviations.
`GAUSS(z)`
• z - a number

## Examples

• `=GAUSS(2)`

The GAUSS function in Sourcetable returns the probability that a member of a standard normal population will fall between the mean and the provided standard deviation from the mean. For example, this would return the probability that a member of a standard normal population would fall between the mean and 2 standard deviations from the mean.

• `=GAUSS(-1)`

The GAUSS Function is useful when performing statistical analysis and calculating probabilities. For example, if a sample population has a mean of 0 and a standard deviation of 1, and would return the probability that a member of the population would be less than -1.

• `=GAUSS(3)`

The GAUSS Function is also useful when calculating z-scores. A z-score is a measure of how many standard deviations a value is from the mean. For example, if a sample population has a mean of 5 and a standard deviation of 2, and would return the probability that a member of the population would have a z-score of 3.

• `=GAUSS(2)`

The GAUSS Function is also useful when calculating confidence intervals. For example, if a sample population has a mean of 10 and a standard deviation of 4, and would return the probability that a member of the population would have a confidence interval of 10 Â± 2.

## Summary

The GAUSS function is used to calculate the probability of a standard normal population member falling between a mean and its standard deviation. It requires a numerical argument to work.

• The GAUSS function calculates the probability that a standard normal population will fall between the mean and a specified z-value from the mean, and returns a number as its argument.
• The number returned by the GAUSS function is the probability.
