## Description of NORM.INV Function

• It is one of the built-in functions in Microsoft Excel.
• This function returns the inverse of the normal distribution for the specified mean and standard deviation.
• You can find the mean using the AVERAGE Function and find the standard deviation using the STDEV Function.

## Syntax

• Here, you will see the syntax of the NORM.INV function.
• To apply this function on your spreadsheet, you have to select a cell and enter the formula in the following format.
• Once you enter the formula, just click on the button to get the result.

=NORM.INV(probability, mean, standard_dev)

Arguments Explanation:

• Probability – It is the probability corresponding to a normal distribution.
• Mean – The arithmetic mean of the distribution.
• Standard_dev – It is the standard deviation of the distribution.

Note:
1) If any argument is non-numeric values such as letters or special characters, then it returns #VALUE! Error.
2) If the probability is less than or equal to 0 or greater than or equal to 1, then this function returns #NUM! Error.
3) If standard_dev is less than or equal to 0, then it returns #NUM! Error.

## Examples

Let’s see some examples to understand this concept quickly.

• Initially, you have to open your Excel workbook on your PC and launch a worksheet that has data.
• You can see the input probability values in Column B, and its mean value is given in Cell F3, and the standard deviation value is printed in Cell F4.
• Apply the above-mentioned formula to get the result, as shown in the following screenshot.
• Finally, we need to click on the button to get the result.
• If any argument is non-numeric values such as letters or special characters, then it returns #VALUE! Error.
• If the probability is less than or equal to 0 or greater than or equal to 1, then this function returns #NUM! Error.

From the above examples, you can learn how to find an inverse of normal distribution using NORM.INV Function.
