Statistical - STDEV.S Function
Description
The STDEV.S function estimates standard deviation based on a sample (ignores logical values and text in the sample).
Syntax
STDEV.S (number1,[number2],...)
Arguments
| Argument | Description | Required/ Optional |
|---|---|---|
| Number1 |
The first number argument corresponding to a sample of a population. You can also use a single array or a reference to an array instead of arguments separated by commas. |
Required |
| Number2, ... |
Number arguments 2 to 254 corresponding to a sample of a population. You can also use a single array or a reference to an array instead of arguments separated by commas. |
Optional |
Notes
STDEV.S uses the following formula −
$$\sqrt{\frac{\sum \left ( x-\bar{x} \right )^2}{n-1}}$$
Where x is the sample mean AVERAGE(number1,number2,…) and n is the sample size.
STDEV.S assumes that its arguments are a sample of the population. If your data represents the entire population, then compute the standard deviation using STDEV.P
The standard deviation is calculated using the "n-1" method.
Arguments can either be numbers or names, arrays, or references that contain numbers.
Logical values and text representations of numbers that you type directly into the list of arguments are counted.
If an argument is an array or reference, only numbers in that array or reference are counted. Empty cells, logical values, text, or error values in the array or reference are ignored.
Arguments that are error values or text that cannot be translated into numbers cause errors.
If you want to include logical values and text representations of numbers in a reference as part of the calculation, use the STDEVA function.
If fewer than two numeric values are supplied to the Function, STDEVA returns the #DIV/0! Error.
If any values that are supplied directly to the Function are text values that cannot be interpreted as numeric values, STDEV.S returns the #DIV/0! Error.
Applicability
Excel 2010, Excel 2013, Excel 2016
