# SKEW.P function

This article describes the formula syntax and usage of the SKEW.P function (function: A prewritten formula that takes a value or values, performs an operation, and returns a value or values. Use functions to simplify and shorten formulas on a worksheet, especially those that perform lengthy or complex calculations.) in Microsoft Excel.

## Description

Returns the skewness of a distribution based on a population: a characterization of the degree of asymmetry of a distribution around its mean.

## Syntax

SKEW.P(number 1, [number 2],…)

The SKEW.P function syntax has the following arguments.

**Number 1, number 2,…** Number 1 is required, subsequent numbers are optional. Number 1, number 2,… are 1 to 254 numbers or names, arrays, or reference that contain numbers for which you want the population skewness.

SKEW.P uses the following equation:

## Remarks

- Arguments can either be numbers or names, arrays, or references that contain numbers.
- Logical values and text representations of numbers that you type directly into the list of arguments are counted.
- If an array or reference argument contains text, logical values, or empty cells, those values are ignored; however, cells with the value zero (0) are included.
- SKEW.P uses the standard deviation of an entire population, not a sample.
- If arguments are values that are not valid, SKEW.P returns the #NUM! error value.
- If arguments use data types that are not valid, SKEW.P returns the #VALUE! error value.
- If there are fewer than three data points, or the sample standard deviation is zero, SKEW.P returns the #DIV/0! Error value.
