NORMDIST

Description Computes the normal distribution.

Syntax NORMDIST (x, mean, st_dev, cumulative)

Argument Description

x The value at which you want to evaluate the function.

mean The arithmetic mean of the distribution.

st_dev The standard deviation of the distribution. It must be a number greater than 0.

cumulative A logical value indicating the type of computation you want NORMDIST to do.

TRUE The function will return the cumulative area from negative infinity to x.

FALSE The function will return the y value for x.

Argument	Description
x	The value at which you want to evaluate the function.
mean	The arithmetic mean of the distribution.
st_dev	The standard deviation of the distribution. It must be a number greater than 0.
cumulative	A logical value indicating the type of computation you want NORMDIST to do.
TRUE	The function will return the cumulative area from negative infinity to x.
FALSE	The function will return the y value for x.

Remarks You may use the STANDARDIZE function to "translate" the first three arguments of this function into a form that can be used in the NORMSDIST function.
