## How does the NORM.S.INV function (DAX) work?

The NORM.S.INV function (DAX) returns the inverse of the standard normal cumulative distribution. The distribution has a mean of zero and a standard deviation of one.

NORM.S.INV(
Probability
)

## How do you use the NORM.S.INV function?

This function will calculate the inverse normal cumulative distribution for a given probability value. The precision of NORM.S.INV depends on the precision of NORM.S.DIST. NORM.S.INV uses an iterative search technique.

## Considerations when using the NORM.S.INV function

The NORM.S.INV function uses only one argument:

1. Probability (required argument) – This is the probability corresponding to the normal distribution. It is the value at which we want to evaluate the inverse function.

## Formula examples using the NORM.S.INV function

EVALUATE { NORM.S.INV(0.908789) }

=NORM.S.INV(0.908789)

=NORM.S.INV( 0.55 )
