Using STDEVA Function in Excel

Nowadays, with robust support from Microsoft Excel applications, calculating standard deviation based on a sample is a breeze using the STDEVA function in Excel.

In this article, Mytour introduces the Excel STDEVA Function to our readers. It is one of the statistical functions widely used in Excel today.

Excel STDEVA Function

Using STDEVA Function in Excel

1. Description and Syntax

This function estimates the standard deviation based on a sample, including both text and logical values. Standard deviation is a measure of the spread of values from the mean.

Syntax:

STDEVA(value1, [value2],...)

Where:

- Value1, [Value2],..: These are the values for which you want to calculate the standard deviation. Value1 is a required parameter, and the remaining parameters are optional, accommodating up to 254 value parameters.

Note:

If the argument is an array or a reference, only the values within that array are considered.

The function encounters an error when the arguments are text or values that cannot be converted.

To exclude both logical and text values from computation, use the STDEV function.

The formula used in STDEVA is as follows:

Where:

+ x represents the sample mean AVERAGE(number1, number2, ...)

+ n is the sample size.

2. Specific Scenario Example

Suppose you need to calculate the standard deviation based on a sample of values in the following data table:

Step 1: In the cell where you want the result -> enter the formula: =STDEVA(B3:B9)

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

Here, logical values are still included in the computation with their respective values.

If all values are either logical or text -> the function returns the result:

In cases where the arguments are text or values that cannot be converted -> the function returns an error result:

Above is a guide along with a specific example when using STDEVA Function in Excel. Using this function helps you estimate the sample standard deviation, including both text and logical values. Best of luck with using this function!

The Count function is a fundamental data counting function and widely used, especially in accounting tasks. Refer to syntax and usage tips for the Count function in the trick article on Mytour, folks.

Alternatively, the function STDEV is also incredibly useful in the tasks of many individuals. Feel free to explore this function in the article about the STDEV function that Mytour has shared.

Frequently Asked Questions

What is the purpose of using the STDEVA function in Excel?

The STDEVA function in Excel is designed to estimate the standard deviation based on a sample. It includes both text and logical values, allowing for a comprehensive analysis of your data set.

How do you correctly use the STDEVA function to calculate standard deviation?

To use the STDEVA function, enter the formula =STDEVA(value1, [value2],...) in the desired cell. Value1 is required, while additional values can be included up to a total of 254 for accurate standard deviation calculations.

Can you give an example of calculating standard deviation with STDEVA in Excel?

Yes, for example, to calculate the standard deviation of values in cells B3 to B9, you would enter =STDEVA(B3) into a cell. After pressing Enter, the function will return the sample standard deviation, including logical values.

What happens if the STDEVA function encounters text or unconvertible values?

If the STDEVA function encounters text or values that cannot be converted, it will return an error result. To avoid this, ensure that only numerical data is included in the calculation, or use the STDEV function instead.
