PHI function - The function returns the value of the density function for a normal distribution in Excel

The following article introduces you to the PHI function - one of the functions in the statistical function group is very popular in Excel.

PHI function - The function returns the value of the density function for a normal distribution in Excel Picture 1

Description: The function returns the value of the density function for a standard normal distribution. Support functions from Excel 2013 onwards.

Syntax: PHI (x)

Inside:

- x: The value you want to determine normalized distribution, is a required parameter .

Attention:

- If x is not numeric -> the function returns the #VALUE! Error value

- If x is an invalid numeric value -> the function returns the #NUM! Error value

For example:

Calculate the value of the density function for a standard normal distribution described in the following data table:
