Statistical - NORM.INV Function
Description
The NORM.INV function returns the inverse of the normal cumulative distribution for the specified mean and standard deviation.
Syntax
NORM.INV (probability,mean,standard_dev)
Arguments
| Argument | Description | Required/ Optional |
|---|---|---|
| Probability | A probability corresponding to the normal distribution. | Required |
| Mean | The arithmetic mean of the distribution. | Required |
| Standard_dev | The standard deviation of the distribution. | Required |
Notes
If any argument is nonnumeric, NORM.INV returns the #VALUE! error value.
If probability < 0 or if probability > 1, NORM.INV returns the #NUM! error value.
If standard_dev ≤ 0, NORM.INV returns the #NUM! error value.
If mean = 0 and standard_dev = 1, NORM.INV uses the standard normal distribution. Refer NORMS.INV.
Given a value for probability, NORM.INV seeks that value x such that NORM.DIST(x, mean, standard_dev, TRUE) = probability. Thus, precision of NORM.INV depends on precision of NORM.DIST.
Applicability
Excel 2010, Excel 2013, Excel 2016
