# STDEV.S function

Excel STDEV.S Function calculates the standard deviation of a given set of numbers. In simple terms, it measures how spread out or dispersed the values are in a dataset. This can be useful in various fields, such as finance, science, and statistics, to analyze data variability.

## Syntax

STDEV.S(number1, [number2], …)

## How to Use

You can use the STDEV.S function in Excel to calculate the standard deviation of a dataset. Here are a few examples to demonstrate its usage:

This formula calculates the standard deviation of the values in cells A1, A2, A3, A4, and A5.

You can also use a cell range (A1:A5) as an argument to calculate the standard deviation of those values.

In this example, STDEV.S calculates the standard deviation for the values in cells B1 to B10.

Remember to provide all the values you want to include in the calculation as arguments to the function. The STDEV.S function will then return the standard deviation of those values.

If you encounter unfamiliar terms or need further information about standard deviation, you can refer to resources like Wikipedia for more detailed explanations. Understanding standard deviation is essential for data analysis and statistics in various fields.
