Calculating standard deviation is a crucial step in data analysis, and Google Sheets provides an easy way to do so. Standard deviation is a measure of the amount of variation or dispersion of a set of values. It is an important statistical concept used in many fields, including finance, economics, and social sciences. In this article, we will explore how to calculate standard deviation on Google Sheets, making it easy for you to analyze your data and make informed decisions.
Why Calculate Standard Deviation?
Standard deviation is used to understand the spread of a dataset, which is essential in many real-world applications. For instance, in finance, it helps investors understand the risk associated with a particular investment. In economics, it helps policymakers understand the impact of economic policies on the economy. In social sciences, it helps researchers understand the spread of opinions and attitudes among a population.
Calculating Standard Deviation on Google Sheets
In this section, we will learn how to calculate standard deviation on Google Sheets using the STDEV function. The STDEV function calculates the standard deviation of a dataset based on a sample of data. To use this function, follow these steps:
1. Select the range of cells that contains the data you want to analyze.
2. Go to the formula bar and type “=STDEV(” followed by the range of cells.
3. Close the parentheses to complete the formula.
4. Press Enter to calculate the standard deviation.
Understanding the Results
Once you have calculated the standard deviation, you can use the result to understand the spread of your dataset. A small standard deviation indicates that the data points are close to the mean, while a large standard deviation indicates that the data points are spread out over a wider range. You can also use the standard deviation to calculate the z-score, which is a measure of how many standard deviations an individual data point is away from the mean.
In the next section, we will explore more advanced techniques for calculating standard deviation on Google Sheets, including how to calculate the standard deviation of a population and how to use the STDEVP function.
How To Calculate Standard Deviation On Google Sheets
Standard deviation is a statistical measure that calculates the amount of variation or dispersion of a set of values from their mean value. It is an important concept in data analysis and is used to understand the spread of a dataset. In this article, we will show you how to calculate standard deviation on Google Sheets.

What is Standard Deviation?
Standard deviation is a measure of the amount of variation or dispersion of a set of values. It is calculated as the square root of the variance of a dataset. The formula for standard deviation is:
Sigma (σ) = √(Σ(x – μ)² / (n – 1))
Where:
- Sigma (σ) is the standard deviation
- x is each value in the dataset
- μ is the mean of the dataset
- n is the number of values in the dataset
Calculating Standard Deviation on Google Sheets
To calculate standard deviation on Google Sheets, you can use the following steps:
- Enter your data into a Google Sheet
- Select the range of cells that contains the data
- Go to the “Insert” menu and select “Function” from the drop-down menu
- In the “Function” dialog box, select “STDEV” from the list of functions
- Enter the range of cells that contains the data in the “Array” field
- Click “OK” to calculate the standard deviation
The standard deviation will be displayed in a new cell in your Google Sheet. You can also use the “STDEVP” function to calculate the standard deviation of a dataset that includes missing values.
Using the STDEV Function
The STDEV function is a built-in function in Google Sheets that calculates the standard deviation of a dataset. The syntax for the STDEV function is:
STDEV(array)
Where:
- array is the range of cells that contains the data
For example, if you want to calculate the standard deviation of the data in cells A1:A10, you would enter the following formula:
STDEV(A1:A10) (See Also: How To Move Decimal Places In Google Sheets)
This will calculate the standard deviation of the data in cells A1:A10 and display the result in a new cell.
Using the STDEVP Function
The STDEVP function is similar to the STDEV function, but it calculates the standard deviation of a dataset that includes missing values. The syntax for the STDEVP function is:
STDEVP(array)
Where:
- array is the range of cells that contains the data
For example, if you want to calculate the standard deviation of the data in cells A1:A10, including missing values, you would enter the following formula:
STDEVP(A1:A10)
This will calculate the standard deviation of the data in cells A1:A10, including missing values, and display the result in a new cell.
Recap
In this article, we have shown you how to calculate standard deviation on Google Sheets using the STDEV and STDEVP functions. We have also discussed the syntax and usage of these functions, as well as how to use them to calculate the standard deviation of a dataset. By following these steps, you can easily calculate the standard deviation of your data and gain a better understanding of the spread of your dataset.
Key Points:

FAQs: Calculating Standard Deviation on Google Sheets
What is standard deviation and why is it important?
Standard deviation is a measure of the amount of variation or dispersion of a set of values. It’s a way to quantify how spread out the data is from the mean value. In finance, standard deviation is often used to measure the risk of an investment, as it shows how much the investment’s value can fluctuate. In Google Sheets, calculating standard deviation can help you understand the variability of your data and make more informed decisions.
How do I calculate standard deviation in Google Sheets?
To calculate standard deviation in Google Sheets, you can use the STDEV function. Simply enter the range of cells containing your data, and the function will return the standard deviation. For example, if your data is in cells A1:A10, you can enter the formula =STDEV(A1:A10) in a new cell to calculate the standard deviation.
What’s the difference between STDEV and STDEVP?
STDEV and STDEVP are both functions that calculate standard deviation, but they differ in how they handle missing values. STDEV ignores missing values and only calculates the standard deviation for the non-missing values. STDEVP, on the other hand, includes missing values in the calculation and returns a N/A error if there are any missing values. Use STDEV if you’re sure there are no missing values in your data, and STDEVP if you’re not sure or if you want to include missing values in the calculation.
Can I calculate standard deviation for a specific range of cells?
Yes, you can calculate standard deviation for a specific range of cells by using the STDEV function with the range of cells as the argument. For example, if you want to calculate the standard deviation for cells A1:A5, you can enter the formula =STDEV(A1:A5). You can also use named ranges or references to specify the range of cells.
How do I use standard deviation in a formula to filter data?
You can use standard deviation in a formula to filter data by using the STDEV function in combination with the IF function. For example, you can use the formula =IF(STDEV(A1:A10)>1,”High Variability”,”Low Variability”) to filter data based on the standard deviation. This formula will return “High Variability” if the standard deviation is greater than 1, and “Low Variability” otherwise.
