Syntax

NORMDIST( <number>, <number>, <number>; <boolean>)

Description

Returns the normal distribution for a certain value with a given mean and standard deviation.

or

Returns the normal density function or the cumulative distribution function for the normal distribution. This function is frequently used to measure the degree of diversity between two data sets.

The function arguments are:

x: The value for which the distribution should be computed (NUMERIC)
Mean: The mean of the distribution (NUMERIC)
Standard deviation: The standard deviation of the distribution (NUMERIC)
Cumulative: Constant indicating the form of the function. If "true" then the cumulative distribution function is used. If "false" then the probability density function is used. (BOOLEAN)

Cumulative/Boolean	Logical argument which defines the type of distribution to be calculated
True	Uses the cumulative distribution function
False	Uses the probability density function

Examples

NORMDIST(#input!Value;#input!Mean;#input!Standard_deviation;cumulative value)

Value	Mean	Standard_deviation	Cumulative value	NORMDIST returns
42	40	1.5	false	0.10934005
42	40	1.5	true	0.908789

Common Errors

#NUM!

-

Occurs if either:

The x value is less than 0
The numerator or denominator is less than 1

#VALUE!

-

Occurs if the argument type isn't numeric
