Excel's STDEV.S Function

Utilizing the STDEV.S Function in Excel

1. Description and Usage Syntax

This function returns the standard deviation based on a sample, disregarding logical and text values. Standard deviation is a measure of the spread of values relative to the mean.

Syntax:

STDEV.S(number1,[number2],...)

Where:

- Number1,[Number2],...: These are the values for which you want to calculate the standard deviation. Number1 is a mandatory parameter, and the rest are optional, with a maximum of 254 number parameters.

Note:
- The STDEV.S function assumes its arguments are a sample of the entire population.
- Standard deviation is calculated using the 'n-1' method.
- The arguments can be numbers, names, or arrays containing numbers.
- When directly entering logical values and presenting text-formatted numbers as function arguments, these values are still considered in the calculation.
- The function returns an error when the arguments are text or error values that cannot be converted.
- If you want to include both logical and text values in the calculation, use the STDEVPA function.
- The equation for STDEV.S utilizes the formula:

Where:
+ x represents the sample mean AVERAGE(number1,number2,...)
+ n is the sample size.

2. Concrete Scenario Example

Imagine you need to calculate the sample standard deviation of values in the data table below:

Step 1: At the cell where you want the result -> enter the formula: =STDEV.S(B3:B8)

Step 2: Press Enter -> the result of the sample standard deviation for the given values is:

In cases where the element values in the set are text or logical -> they are ignored:

Here, Mytour has guided you through specific examples of using STDEV.S Function in Excel. Utilizing this function helps you compute the sample standard deviation, excluding logical and text values in Excel. Wishing you success in applying this formula.

Among the fundamental functions, the Count function is one you can't overlook when starting to learn Excel. It's a data counting function widely used in Excel. Explore more about the Count function syntax and usage in the Mytour tricks and tips article.

Frequently Asked Questions

What is the purpose of the STDEV.S function in Excel?

The STDEV.S function in Excel calculates the standard deviation of a sample, providing insights into the spread of data points relative to the mean. It helps in data analysis and ensures accurate statistical calculations.

How do I properly use the STDEV.S function in Excel?

To use the STDEV.S function, enter the formula as STDEV.S(number1, [number2], ...). Here, number1 is required, and you can include up to 254 additional numbers, allowing for flexible data input for analysis.

Can I include text or logical values when using STDEV.S in Excel?

No, the STDEV.S function ignores text and logical values when calculating standard deviation. To include logical and text values, you should use the STDEVPA function instead.

What is the formula used in STDEV.S to calculate standard deviation?

The formula for STDEV.S calculates standard deviation using the sample mean and the sample size. It applies the 'n-1' method, ensuring accurate statistical analysis for data samples.
