How to use the VARP function in Excel


In this article, we will learn how to use VARP Function in Excel. VARP function is a statistical function which returns the numerical variance value for the array of data population given in as input. In simple words, get the estimated variation of population of the data. Use VARP or newer VAR.P function if data represents the entire population.

Syntax:

=VARP(number1,number2,..)

number : number or array given as cell reference
Different VAR function in Excel and its usage.

Name Data set Text and logicals
VAR Sample Ignored
VARP Population Ignored
VAR.S Sample Ignored
VAR.P Population Ignored
VARA Sample Evaluated
VARPA Population Evaluated

Example:
All of these might be confusing to understand. So, let's test this formula via running it on the example shown below. Here we have some numbers to test the VARP function in Excel.
Use the formula:

=VARP(C1:C17)

Here the array of values is given as cell reference. You can also input values as numbers.

Here the function ignores blank cells, TRUE and FALSE logic values and text values. The VAR.P function returns 267.1071 as population variance whereas VAR function returns 287.6538 as sample population.

What is the Difference in VAR, VARS, VAR.S (all are same) and VARP or VAR.P.
The denominatore in VAR, VARS,VAR.S is n-1. Where n is the number of observations. Where  VAR.P has denominator n.

VAR/VARS/VAR.S VARP/VAR.P
=summation[(x-x)2/(n-1)] =summation[(x-x)2/n]

VAR.S is used for sample data. VAR.P is used for population data. 

Here are some observational notes shown below.
Notes:

  1. The formula only works with numbers, text and Logic values as argument.
  2. Use the VAR, VARS and VAR.S function for the sample data.
  3. The VARP function ignores text, logic values and blank cells.
