The `VARP` function in Excel is used to calculate the variance of an entire population of data. If you’re dealing with a sample of a population, instead of the entire population, you would use the `VAR` function (or `VAR.S` in Excel 2010 and later).
Here’s how you can use the `VARP` function:
Syntax
VARP(number1, [number2], ...)
- number1: This is the first number or cell reference that you want to calculate the variance for.
- [number2], …: Additional numbers or cell references for which you want to calculate the variance. You can include up to 254 numbers or cell references in total.
Steps to Use VARP
- Select the Cell: Click on the cell where you want the result of the variance to appear.
- Enter the Function:
- You can start with an equal sign `=`, then type `VARP(`.
- Input your data either by typing numbers directly separated by commas or by selecting cell ranges. For example, `VARP(A1:A10)` calculates the variance for the numbers in cells A1 through A10.
- Close the Parenthesis: After entering your data or selecting your cell ranges, close the parenthesis `)` to complete the function.
- Press Enter: Hit the Enter key to compute the variance of your data.
Example
Suppose you have a data set in cells B2 through B6, and you want to calculate the variance for this entire population:
=VARP(B2:B6)
Important Notes
- Populated Data: The `VARP` function is intended for use when you have data that represents an entire population. If you’re working with a sample from the population, `VAR.S` (or `VAR` in older Excel versions) is more appropriate.
- Excel Versions: The `VARP` function is available in all versions of Excel, but starting in Excel 2010, you might prefer to use `VAR.P` as it follows the newer naming convention, although `VARP` still works for backward compatibility.
Using this function appropriately will help you perform statistical analysis on your entire data set, providing insights into the dispersion or variability within your population.
