When working with data, we often need some metrics to help us figure out what kind of data we have. Metrics that show how many people are in a group are called averages, mean, mode, and standard deviation. Google Sheets has a lot of useful built-in formulas that you can use to do a lot of statistical math. Will show a simple procedure.

## What is Standard Deviation?

The standard deviation tells you how much the data is off the mean, which is the middle. For example, suppose you have a class of 50 students and their scores on a math test. It means that if the mean score is 70, and the standard deviation is 10, most of the students’ scores are in the range of +/- 10 from the mean score (i.e., most students have marks between 60 and 80).

The standard deviation is usually found by taking the square root of the variance.

## Use STDEV in a certain way

**When you use the STDEV function in Google Sheets, here are some things to keep in mind:**

1. STDEV usually doesn’t care about string parameter values (or cells that include text values). Because, of course, if all of your parameter values are strings, you will get an error message.

2. The STDEV formula is used to figure out the standard deviation. If you want to find the standard deviation for a group of people, you will need to use the STDEVP formula instead.

3. You must have at least two numbers in the arguments for the formula to work. There will be a #DIV/0! Error if you don’t, so don’t do this!

4. When you use STDEV to figure out the Standard deviation, blank cells in your chosen range aren’t considered.

## Other Standard Deviation Formula in Google Sheets

- STDEVP: This is used to figure out the Standard Deviation of a group of people.

STDEVA: This is used to figure out the Standard Deviation when text values are thought of as 0. In some cases, this could be useful if you have dashes or text like zero in a cell and want them to count as 0.

- STDEVPA: This is used to figure out the standard deviation when text values are thought of as 0.

**In Google Sheets, how do you figure out standard deviation?**

In Google Sheets, it can be helpful to use statistical calculations to learn more about the samples and the populations they come from, which can help you figure out what they are like.

An example of this is the standard deviation, which tells us how many different things there are in an instance.

When there are a lot of different numbers in a sample, it means that there are a lot of other numbers in it. This is called having a high standard deviation.

Google Sheets makes it easy to figure out the standard deviation because it has a built-in formula. So how do I learn how?

**It’s the first step:**

To figure out standard deviation, the formula we will use is called STDEV ().

“=STDEV(” is how you write the formula in the cell you want to add the standard deviation calculation to.”

**Step two:**

After you write the open parenthesis, use the mouse to select the range in the spreadsheet to calculate the standard deviation. It will be added as a parameter to the formula you’re writing. Will reference the content in the procedure you write.

**Step three:**

Enter when you’re done with your formula. You’ll see it in the cell. The standard deviation for that sample will be there.

Any time you change the data in the range you’ve put in, we will recalculate the standard deviation.
