NORMINV

Syntax:

NORMINV ( probability , mean , standard-deviation )

Description: Computes the inverse of the normal distribution for the specified mean and standard deviation. NORMINV uses an iterative search technique.

Arguments:

Name

Type

Description

probability

number

The probability corresponding to the normal distribution.

mean

number

The arithmetic mean of the distribution.

standard-deviation

number

The standard deviation of the distribution.

Return Type and Value: number – The inverse of the normal distribution for the specified mean and standard deviation.

However, if

  • probability < 0 or if probability > 1, #NUM! is returned.

  • standard-deviation ≤ 0, #NUM! is returned.

  • The search has not converged after an implementation-defined number of iterations, #N/A is returned.
