NORMDIST

See Also

Returns the normal distribution for the specified mean and standard deviation. This function has a very wide range of applications in statistics, including hypothesis testing.

Syntax

NORMDIST(x,mean,standard_dev,cumulative)

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.

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