NormDist() returns the cumulative normal distribution for the specified mean and standard deviation. If mean = 0 and standard_dev = 1, the function returns the standard normal distribution.
Syntax:
NORMDIST(value, [mean], [standard_dev], [cumulative])
Return data type: number
Arguments:
| Argument | Description | 
|---|---|
| value | The value at which you want to evaluate the distribution. | 
| mean | Optional value stating the arithmetic mean for the distribution. If you do not state this argument, the default value is 0. | 
| standard_dev | Optional positive value stating the standard deviation of the distribution. If you do not state this argument, the default value is 1. | 
| cumulative | You can optionally select to use a standard normal distribution or a cumulative distribution. 0 = standard normal distribution 1 = cumulative distribution (default) | 
 This function is related to the NormInv function in 
 the following way: 
If prob = NORMDIST(value, m, 
 sd), then NORMINV(prob, m, sd) = value
Limitations:
All arguments must be numeric, else NULL will be returned.
