VAR.S function

PRO BASIC

The VAR.S function in Jspreadsheet Formulas Pro is used to calculate the variance from a sample of data. It gives a fair estimate of the population variance, which is a measure of how much individual data points in a group differ from the group's average. This function is particularly useful in statistical analysis to understand data dispersion and volatility. It can be easily used in Jspreadsheet Formulas Pro to analyze your data sets.

Documentation

Calculates the variance based on a sample. Provides an unbiased estimate of the population variance.

Syntax

VAR.S(number1, [number2], ...)

Parameter	Description
`number1`	The first number or range of numbers that you want to calculate the variance of. At least two numeric values are required.
`numberN`	Additional numbers or ranges of numbers that you want to include in the calculation. You can include up to 255 numbers or ranges.

Behavior

The VAR.S function calculates the variance based on a sample. Variance is a measure of dispersion, showing how far the numbers are spread out from their average. Here's how VAR.S handles different types of inputs:

Numbers: VAR.S treats numeric values normally, using them in its variance calculation.
Text and Booleans: Text values are ignored, but boolean values are treated as numbers (TRUE=1, FALSE=0).
Empty Cells: VAR.S ignores empty cells completely. They do not impact the calculation.
Errors: If any cell reference or direct input has an error, the VAR.S function will also return an error.

Common Errors

Error	Description
#DIV/0!	This error occurs when there are less than two data points in the sample or all the data points are non-numeric (like text, booleans, or blank cells).
#VALUE!	This error is displayed when the function receives a value of a different type than expected.
#N/A	This error occurs when there's no available data to calculate variance.

Best practices

Always ensure you have at least two numeric data points in the range you're calculating the variance for, as variance requires comparison between at least two values.

Be aware that VAR.S ignores text values. If you need these to be considered as zero, convert them to numeric values before calculation.

To avoid errors, ensure that your sample data doesn't contain error values, as they would cause the VAR.S function to return an error as well.

It's a good practice to check your data for outliers as they can significantly affect the variance.

Usage

A few examples using the VAR.S function.

VAR.S(1,2,3,4,5)              // Returns 2.5 - sample variance of these numbers
VAR.S(A1:A10)                 // Variance of values in range A1:A10
VAR.S(B1:B10, C1:C10)         // Variance across two ranges
VAR.S(10, TRUE, FALSE)        // TRUE=1, FALSE=0 → variance includes booleans
VAR.S("5","7",3,9)            // Text is ignored, numbers included
