SKEW.P function

PRO

The SKEW.P function in Jspreadsheet Formulas Pro is a statistical tool that provides the population skewness of a distribution - a quantification of how asymmetric the data set is. If the skewness is negative, the data is skewed left, while a positive skewness indicates data skewed right. This function helps you understand the nature of your data distribution better, providing insights into its overall shape and balance.

Documentation

Returns the population skewness of a distribution, which is a measure of asymmetry.

Syntax

SKEW.P(number1, [number2], ...)

Parameter	Description
`number1`	The first number or range of numbers for which to calculate the population skewness.
`numberN`	Optional. Additional numbers or ranges of numbers for which to calculate the population skewness. Up to 255 arguments can be provided.

Behavior

The SKEW.P function calculates the skewness of a given dataset. Skewness is a measure of the asymmetry of the probability distribution of a real-valued random variable about its mean. Here is how it behaves with different types of data:

Empty cells: The SKEW.P function ignores empty cells.
Text: The SKEW.P function cannot handle text and will return an error if any cell in the range or array contains text.
Booleans: Boolean values are treated as 1 for TRUE and 0 for FALSE.
Errors: If any cell in the range or array contains an error, SKEW.P will return an error.
Data limitation: The SKEW.P function requires at least 2 numeric data points in the dataset. If the dataset contains fewer than two data points, the function will return an error.

Common Errors

Error	Description
#DIV/0!	Occurs when less than two numeric data points are provided.
#VALUE!	Occurs when non-numeric data points are included in the dataset.
#N/A	Occurs when the function cannot find the specified value or cell.

Best practices

Always ensure that the dataset provided to the SKEW.P function contains at least two numerical values, to avoid a #DIV/0! error.

Exclude non-numeric values from the dataset to prevent a #VALUE! error.

Use the ISNUMBER function to check whether cells contain numeric values before using them in SKEW.P.

For a sample of a population, use SKEW instead of SKEW.P as SKEW.P is biased and is appropriate only for population, not for a sample.

Usage

A few examples using the SKEW.P function.

SKEW.P(A1:A100)
// Returns the population skewness of the values in cells A1 through A100
SKEW.P(1,2,3,4,5)
// Returns 0, since the data is symmetric
SKEW.P(-1,0,1,2.5)
// Returns approximately 0.243942852, indicating a slight right skew
