Advanced Excel Statistical - VAR.P Function

Description

The VAR.P function calculates variance based on the entire population (ignores logical values and text in the population).

VAR.P (number1, [number2]...)

Argument	Description	Required/ Optional
Number1	The first number argument corresponding to a population.	Required
Number2, ...	Number arguments 2 to 254 corresponding to a population.	Optional

The equation for VAR.P is −

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

Where x is the sample mean AVERAGE (number1, number2…) and n is the sample size.
VAR.P assumes that its arguments are the entire population. If your data represents a sample of the population, then compute the variance by using VAR.S
Arguments can either be 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.
If any values that are supplied directly to the Function are text values that cannot be interpreted as numeric values, VAR.P returns the #VALUE! error value.
If none of the values that have been supplied to the function are numeric, VAR.P returns the #DIV/0! error value.
If you want to include logical values and text representations of numbers in a reference as part of the calculation, use the VARPA function.
