Compatibility - VARP Function

The VARP function replaces the VAR.P function in Excel 2010.

Description

The function calculates the variance based on the entire population.

VARP (number1,[number2],...)

Argument	Description	Required/ Optional
Number1	The first number argument corresponding to a population.	Required
Number2...	Number arguments 2 to 255 corresponding to a population.	Optional

The equation for VARP is −

$$\frac{\sum(x-\bar{x})^2}{n}$$

Where x is the sample mean AVERAGE (number1,number2,…) and n is the sample size.
If you want to include logical values and text representations of numbers in a reference as part of the calculation, use the VARPA function.
VARP assumes that its arguments are the entire population. If your data represents a sample of the population, then compute the variance by using VAR.
Arguments can be either numbers or names, arrays, or references that contain numbers.
Logical values and text representations of numbers that you type directly into the list of arguments are counted.
If an argument is an array or reference, only numbers in that array or reference are counted. Empty cells, logical values, text, or error values in the array or reference are ignored.
Arguments that are error values or text that cannot be translated into numbers cause errors.
