WorksheetFunction.Norm_Dist method (Excel)
Returns the normal distribution for the specified mean and standard deviation. This function has a wide range of applications in statistics, including hypothesis testing.
Syntax
expression.Norm_Dist (Arg1, Arg2, Arg3, Arg4)
expression A variable that represents a WorksheetFunction object.
Parameters
| Name | Required/Optional | Data type | Description |
|---|---|---|---|
| Arg1 | Required | Double | X - The value for which you want the distribution. |
| Arg2 | Required | Double | Mean - The arithmetic mean of the distribution. |
| Arg3 | Required | Double | Standard_dev - The standard deviation of the distribution. |
| Arg4 | Required | Boolean | Cumulative - A logical value that determines the form of the function. If cumulative is True, Norm_Dist returns the cumulative distribution function; if False, it returns the probability mass function. |
Return value
Double
Remarks
If mean or standard_dev is nonnumeric, Norm_Dist returns the #VALUE! error value.
If standard_dev ≤ 0, Norm_Dist returns the #NUM! error value.
If mean = 0, standard_dev = 1, and cumulative = TRUE, Norm_Dist returns the standard normal distribution, Norm_S_Dist.
The equation for the normal density function (cumulative = FALSE) is:
When cumulative = TRUE, the formula is the integral from negative infinity to x of the given formula.
