NORM.S.INV()/NORMSINV()
Syntax. NORM.S.INV(probability)
Definition. This function returns the quantile of the standard normal distribution. The standard normal distribution has a mean of 0 and a standard deviation of 1.
Arguments
probability (required). A probability associated with the standard normal distribution
Note
If probability isn’t a numeric expression, the NORM.S.INV() function returns the #VALUE! error.
If probability is less than 0 or greater than 1, the NORM.S.INV() function returns the #NUM! error. If probability has a value, NORM.S.INV() looks for the value z so that NORMSDIST(z) = probability.
Therefore, the accuracy of NORM.S.INV() depends on the accuracy of NORM.S.DIST(). NORM.S.INV() uses an iterative search technique. If the search ...
