Syntax
NORMDIST(x, mean, standard_deviation, cumulative)
Parameters
| Name | Type | Description |
|---|---|---|
| x | numeric |
The value for which you want to calculate the probability. |
| mean | numeric | The mean value of the data set. |
| standard_deviation | numeric |
The standard deviation of the data set. The standard_deviation value must be greater than 0. |
| cumulative | logical |
Specify T to calculate the probability that a random variable is less than or equal to x (cumulative probability), or F to calculate the probability that a random variable is exactly equal to x (simple probability). |
Output
Numeric.
