# NORM.DIST

NORM.DIST(x, mean, standard_dev, cumulative)

Returns the probability distribution function OR the cumulative probability function for a normal distribution.

 x The number from the distribution. mean The arithmetic mean of the distribution. standard_dev The standard deviation of the distribution. cumulative A logical value indicating the type of function to use:False (or 0) = [[probability distribution function]] (equal to)True (<> 0) = [[cumulative probability function]] (equal to or less than)

 REMARKS
 * This function was added in Excel 2010 to replace the NORMDIST function.* For an illustrated example refer to the page under [[Distributions]]* The normal distribution is a [[continuous distribution]]* If "cumulative" = False, then the height of the curve at "x" is returned.* If "cumulative" = True, then the area under the curve to the left of "x" is returned.* You can use the NORM.S.DIST function to* You can use the NORM.S.INV function to* You can use the NORM.INV function to* For the Microsoft documentation refer to support.microsoft.com
