# How to Use SUMSQ in Google Sheets

SUMSQ is a built-in function in Google Sheets that calculates the sum of the squares of a set of numbers. This function can be useful in various mathematical and statistical applications, such as calculating variance or standard deviation. Here's how to use SUMSQ in Google Sheets:

- Open your Google Sheets document or create a new one.
- Click on a cell where you want the result of the SUMSQ function to be displayed.
- Type the formula
`=SUMSQ(number1, number2, …)`

in the cell, where "number1, number2, …" represents the numbers you want to calculate the sum of squares for. You can also use cell references, ranges, or a combination of both.

For example, if you want to calculate the sum of squares for the numbers 2, 3, and 4, you would enter the formula `=SUMSQ(2, 3, 4)`

.

Example:

Let's say you have the following data in cells A1 to A5:

```
2
3
4
5
6
```

To calculate the sum of squares for these numbers, you can use the SUMSQ function in the following way:

- Click on an empty cell, for example, B1.
- Type the formula
`=SUMSQ(A1:A5)`

in the cell B1 and press Enter.

Google Sheets will now display the result, which is 90, in the cell B1. This is the sum of the squares of the numbers in the range A1:A5 (2^2 + 3^2 + 4^2 + 5^2 + 6^2 = 90).
