The standard deviation measures how clustered or spread out the data is in relation to the mean. You may acquire a numerical scale of how spread your data is by calculating standard deviation.

Though you may manually develop a formula in Google Sheets to compute the standard deviation of a data collection, you can alternatively save time by utilizing the STDEV function. Continue reading to learn how to utilize the STDEV function in Google Sheets to compute standard deviation. ​​

## STDEV Function in Google Sheets

Google Sheets use the same sophisticated technique for calculating standard deviation as Excel. Fortunately, the STDEV function is simple to use. This function’s syntax is as follows:

`=STDEV(value1, value2, ...)`

The STDEV function accepts the cells you wish to include in your sample and computes the standard deviation for that sample. STDEV values may be entered as single cells or ranges of cells.

If your intended sample does not fit in a single range, you may add a range followed by single cells as seen below:

`=STDEV(A1:C11, E8, G2)f`

Because the STDEV function does not operate on text values, if you have designated a cell in your sample that includes text, STDEV will disregard it. In the STDEV function, you may also enter numbers instead of cells.

## How to Use the STDEV Function in Google Sheets

Let’s look at how the STDEV function works now. In this spreadsheet, for example, we have the grades of 10 students on three distinct disciplines. The purpose is to determine which topic has more consistent marks by calculating the standard deviation for each of these subjects.

1. Choose the cell in which you wish to display the standard deviation. In this example, we’ll choose cell B12.
2. Enter the following formula in the formula bar: =STDEV(B2:B11) The STDEV function is used in this formula to determine the standard deviation for the integers in cells B2 to B11. B2:B11 should be replaced with your preferred cell range.
4. Take hold of the fill handle and place it on the cells where you wish to compute the standard deviation. In this case, there are cells C12 and D12.
How to Stop Google From Showing You Personalized Search Results

We now know the standard deviation for each of the three subjects. A small number indicates a concentrated dataset, whereas a larger number indicates a scattered dataset.

Looking at the figures in this example, you can see that the kids are on around the same level in English, but there is a big gap in the students’ arithmetic ability.
