Introduction
Google Sheets is a powerful tool for organizing and analyzing data. One of the many functions it offers is the DVARP function. This function allows you to calculate the variance of a population based on a specified criteria. In simpler terms, it helps you find out how spread out your data is from the average.
In this article, we’ll break down the steps to use the DVARP function in Google Sheets in a way that’s easy to understand, even for 5th-grade students.
When to Use the DVARP Function
The DVARP function comes in handy when you have a large set of data and you want to analyze a specific subset of that data. For example, let’s say you have a list of students’ scores, and you want to know the variance of scores for only the students who scored above a certain mark.
How to use DVARP function in Google Sheets
- Type “=DVARP” or go to the “Insert” tab ➝ “Function” ➝ “Database” ➝ “DVARP”.
Syntax
DVARP(database, field, criteria)
- database – The array or range containing the data to consider, structured in such a way that the first row contains the labels for each column’s values.
- field – Indicates which column in database contains the values to be extracted and operated on.
- field may either be a text label corresponding to a column header in the first row of database or a numeric index indicating which column to consider, where the first column has the value 1.
- criteria – An array or range containing zero or more criteria to filter the database values by before operating.
Example:
Step 1: Open Your Google Sheet
Step 2: Select a Cell and Enter the Function
Step 3: Press Enter: Hit the Enter key to apply the function

FAQ’s
Q: Can I use the DVARP function with text data?
A: No, the DVARP function is designed for numerical data. If you try to use it with text, it will return an error.
Q: What does “variance” mean?
A: Variance measures how spread out a set of data points are. In simpler terms, it tells you how much the individual numbers in a dataset differ from the average.
Q: Can I use the DVARP function on a mobile device?
A: Yes, you can use the DVARP function on Google Sheets mobile app. Simply enter the function in a cell, similar to how you would on a computer.
Q: How do I update the data range in the DVARP function?
A: If your dataset expands or contracts, remember to update the database range in your DVARP function. Using outdated ranges can lead to inaccurate results. Simply edit the range directly in the formula.
