# NORM.INV

Formulas / NORM.INV
Calculate the inverse of the normal cumulative distribution.
`NORM.INV(probability,mean,standard_dev)`
• Probability - required, probability associated with the normal distribution
• Mean - required, average of the distribution
• Standard_dev - required, standard deviation of the data set

## Examples

• `=NORM.INV(0.5, 0, 1)`

Using the NORM.INV function requires three arguments: the probability, the mean and the standard deviation. For example, to find the inverse of the normal cumulative distribution for a probability of 0.5, a mean of 0 and a standard deviation of 1, the syntax of the function can be found above.

• `=NORM.INV(0.8, 10, 3)`

The NORM.INV function can also be used to find the value of a given probability for a normal distribution with a known mean and standard deviation. For example, if the mean is 10 and the standard deviation is 3, the syntax of the function to find the value of a probability of 0.8 would be found above.

• `=NORM.INV(12, 10, 3)`

The NORM.INV function can also be used to calculate the probability of a given value for a normal distribution with a known mean and standard deviation. For example, if the mean is 10 and the standard deviation is 3, the syntax of the function to find the probability of a value of 12 would be found above.

• `=NORM.INV(0.95, 10, 3)`

The NORM.INV function can also be used to calculate the value at which a given probability occurs for a normal distribution with a known mean and standard deviation. For example, if the mean is 10 and the standard deviation is 3, the syntax of the function to find the value of a probability of 0.95 would be found above.

## Summary

The NORM.INV function is used to calculate the inverse of the normal distribution given the probability, mean, and standard_dev arguments. It is a necessary tool for data analysis.

• The NORM.INV function returns the probability threshold value for a given probability input within the range (0,1).
• The NORM.INV function calculates the inverse of the normal distribution, allowing users to determine the probability of a given value occurring.
