Excel - STDEV.S Function
STDEV.S Function
The Excel STDEV.S function calculates the standard deviation of a specific sample taken from the massive numeric dataset. However, logical and text values are skipped during its calculations. The core difference between the STDEV.S and STDEV.P is that the sum of squared differences from the average is partitioned by the n-1 in the STDEV.S function and in the later version, the sum of squares differences are partitioned by n.
The STDEV.S interchanged the STDEV function in Excel 2010. In the older version, you can STDEV function.
Compatibility
This advanced Excel function is compatible with the following versions of MS Excel
- Excel for Microsoft 365
- Excel for Microsoft 365 for Mac
- Excel for the web
- Excel 2024
- Excel 2024 for Mac
- Excel 2021
- Excel 2021 for Mac
- Excel 2019
- Excel 2016
- Excel 2013
- Excel 2010
Syntax
The syntax of the STDEV.S function is as follows −
=STDEV.S(number1,[number2],...)
Arguments
You can use the following arguments with the STDEV.S function −
| Argument | Description | Required/ Optional |
|---|---|---|
| Number1 | It represents the first number argument that may be a single array or cell range that points to numeric values. | Required |
| Number2, ... | It may contain the number 2 argument up to the 254 arguments for a sample. | Optional |
Points to Remember
- STDEV.S uses the following formula −
√∑(x−ˉx)2n−1
Where x is the sample mean AVERAGE(number1,number2,…) and n is the sample size.
- The STDEV.S function utilizes the "n-1" method to compute the standard deviation.
- This function interprets the sample taken from the massive dataset.
- The text string, blank cells, and Boolean values are not counted in the given array or the reference argument. Only numbers are counted in the defined array or cell references.
- If the specific cell contains the error in the defined cell range or the given array, then the STDEV.S function returns the same error.
- If only one data point is specified in the array, then the STDEV.S function returns the #DIV/0!.
Examples of STDEV.S Function
Practice the following examples to learn the use of the STDEV.S function in Excel.
Example 1: How do you use the STDEV.S Function in Excel?
Solution
In this example, we will explore the core concept of the STDEV.S function to calculate the sample standard deviation rounded to three digits.
Step 1 − First, assume the sample data which is written in the cell range B3:B12 comprises numbers only.
Therefore, the sample standard deviation is 34.17497 returned by the STDEV.S function.
Step 2 − Afterward, round the final result to the three digits using the ROUND function. Double-click on the D11 cell and enter the formula =ROUND(D10,3). In this expression, the D10 gives the computed result of the STDEV.S function and 3 indicates only three digits occurred after the decimal point.
Therefore, the resulting value is 34.175.
Example 2
If only one data point is specified in the array, then the STDEV.S function returns the #DIV/0!.
Solution
You may write the formula =STDEV.P(1) in the B3 cell and press the Enter tab. In this expression, only one number is passed to the argument.
After hitting the Enter tab, the resulting value is #DIV/0!.
