Excel NORM.S.INV Function
The NORM.S.INV calculates and returns the inverse of the standard normal cumulative distribution that has an arithmetic mean of 0 and standard deviation of 1 with a given probability.
Syntax
=NORM.S.INV(probability)
Arguments
- probability (required): The probability corresponding to the normal distribution. It is the value at which you want to evaluate the inverse function.
Return Value
The NORM.S.INV function returns a numeric value.
Function Notes
- The #VALUE! error occurs if probability is nonnumeric.
- The #NUM! error occurs if probability ≤ 0 or probability ≥ 1.
Example
To get the inverse of the standard normal cumulative distribution with the probabilities as shown in the screenshot below, please copy or enter the formula below in the top cell C3, and press Enter to get the first result:
=NORM.S.INV(B3)
√ Note: After entering the formula, drag the fill handle down to apply the formula to the below cells.
Note that for the normal cumulative distribution (probability) that is calculated with NORM.S.DIST(z, TRUE), the NORM.S.INV function will return the z value based on the probability result. See screenshot:
NORM.S.INV VS. NORM.INV
- NORM.S.INV uses the standard normal distribution which is a special case of the normal distribution where the mean is 0 and the standard deviation is 1;
- NORM.INV uses the normal distribution with the mean and standard deviation you specified.
