Advanced Excel Statistical - VAR.S Function

Description

Estimates variance based on a sample (ignores logical values and text in the sample).

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

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

VAR.S uses the following formula −

$$\frac{\sum \left ( x-\bar{x} \right )^2}{\left ( n-1 \right )}$$

Where x is the sample mean AVERAGE (number1,number2,…) and n is the sample size.
VAR.S assumes that its arguments are a sample of the population. If your data represents the entire population, then compute the variance by using VAR.P
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.
Arguments that are error values or text that cannot be translated into numbers cause errors.
If you want to include logical values and text representations of numbers in a reference as part of the calculation, use the VARA function.
If fewer than 2 numeric values have been supplied to the Function, VAR.S returns the #DIV/0! error value.
If any values that are supplied directly to the Function are text values that cannot be interpreted as numeric values, VAR.S returns the #VALUE! error value.
