STDEVP

Measures the population standard deviation to analyze data variability.

The STDEVP function returns the population standard deviation of a dataset. It measures how widely values are dispersed from the mean, assuming the data represents the entire population. The calculation uses (n) in the denominator.

Syntax

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

Arguments

The STDEVP function syntax has the following arguments:

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

Example

STDEVP(10, 20, 30, 40, 50)
// Returns 14.14

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

STDEVP function

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

Excel Equivalent

STDEVP

STDEVS calculates the sample standard deviation using (n − 1) in the denominator and should be used when working with a sample dataset, whereas STDEVP calculates the population standard deviation using (n) in the denominator and should be used when working with the entire population.

FAQs

Q1. How is STDEVP calculated?

STDEVP (Population Standard Deviation) is calculated by taking the square root of the sum of squared deviations from the mean, divided by (n).

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 population standard deviation, which is the square root of the population variance.
