variance

Type

function

Summary

Returns the sample variance of a list of numbers.

Syntax

variance(<numbersList>)

Description

Use the variance function to analyze the amount of spread in a list of numbers.

The variance function was added in LiveCode 6.1 to complement the standardDeviation function. The variance is a measure of how widely distributed the numbers in the numbersList are.

If a math operation on finite inputs produces a non-finite output, an execution error is thrown. See math operations for more information.

Parameters
