NORM.S.DIST function

Returns the standard normal distribution (has a mean of zero and a standard deviation of one).

Use this function in place of a table of standard normal curve areas.

Syntax – Standard Normal Distribution

NORM.S.DIST(z,cumulative)

The NORM.S.DIST function syntax has the following arguments:

  • Z     Required. The value for which you want the distribution.

  • Cumulative     Required. Cumulative is a logical value that determines the form of the function. If cumulative is TRUE, NORMS.DIST returns the cumulative distribution function; if FALSE, it returns the probability mass function.

Remarks

  • If z is nonnumeric, NORM.S.DIST returns the #VALUE! error value.

  • The equation for the standard normal density function is:
