Reference > Functions > NORMDISTCDF function

Returns the cumulative distribution function for the specified mean and standard deviation.

Syntax

NORMDISTCDF(x,mean,standard_dev)

where

X	is the value for which you want the distribution.
Mean	is the arithmetic mean of the distribution.
Standard_dev	is the standard deviation of the distribution (must be greater than 0.)

The result of normdistcdf is the integral of the NORMDIST function from negative infinity to x. It can also be represented by:

NORMDISTCDF is equivalent to Excel's NORMDIST function with the cumulative parameter set to TRUE.
