Understanding data is crucial in any field. One of the most common statistical tools used for this purpose is the standard deviation. It’s a measure that quantifies the variation or dispersion of a set of values. In this blog post, we will show you how to find the standard deviation in Google Sheets.

## What is Standard Deviation?

Standard deviation is a measure that is used to quantify the amount of variation or dispersion of a set of values. A low standard deviation means that the values tend to be close to the mean (also called the expected value) of the set, while a high standard deviation means that the values are spread out over a wider range.

## Finding Standard Deviation in Google Sheets

Google Sheets is a fantastic tool that has built-in functionality to calculate standard deviation. There are two common functions used to calculate standard deviation in Google Sheets: **STDEVP** and **STDEV.S**. The STDEVP function is used when your data represents the entire population. STDEV.S is used when your data is a sample of the entire population.

Here’s how to use these functions:

### Using the STDEVP Function

If your data represents the entire population, you can use the STDEVP function to calculate the standard deviation. The syntax for this function is: **=STDEVP(value1, [value2], …)**

=STDEVP(A2:A100)

### Using the STDEV.S Function

If your data is a sample of the entire population, use the STDEV.S function to calculate the standard deviation. The syntax for this function is: **=STDEV.S(value1, [value2], …)**

=STDEV.S(A2:A100)

## Conclusion

In this blog post, we learned how to calculate standard deviation in Google Sheets using the **STDEVP** and **STDEV.S** functions. Depending on whether your data set represents the entire population or a sample, you will use either one of these functions. This is a fundamental skill for anyone working with data. Google Sheets makes it quite simple to quickly calculate this important statistical measure.
