STDEVS

Measures the sample standard deviation to analyze data variability.

The STDEVS function returns the sample standard deviation of a dataset. It measures how widely values are dispersed from the mean, assuming the data represents a sample of a larger population. The calculation uses (n − 1) in the denominator to provide an unbiased estimate.

Syntax

STDEVS(number1, [number2], ...)

Arguments

The STDEVS function syntax has the following arguments:

• number1, number2, ... - The numeric values for which you want to calculate the sample standard deviation.

Example

STDEVS(10, 20, 30, 40, 50)
// Returns 15.81

You can use the STDEVS function to analyze how widely values are spread from the mean by calculating the sample standard deviation for metrics such as sales, revenue, or performance scores.

STDEVS function

We used the SELECT function to select a range of columns from 1 to 4 for the 'Revenue' measure (2022 Revenue - 2025 Revenue)

STDEVS

STDEV is the legacy version of the STDEVS function and works similarly. It can be used in place of STDEVS for sample standard deviation calculations.

FAQs

Q1. How is STDEVS calculated?

STDEVS (Sample Standard Deviation) is calculated by taking the square root of the sum of squared deviations from the mean, divided by (n − 1).

Where:

• x = each value in the dataset

• = mean of the values

• n = number of values

It measures how widely the values are spread from the mean by calculating the sample standard deviation, which is the square root of the sample variance.
