VAR function

The VAR function in Jspreadsheet Formulas Pro is a mathematical tool that helps you estimate the variance based on a sample of data. Variance is a statistical concept that measures how much individual numbers in a dataset vary or deviate from the average. In simpler terms, it tells you how spread out your data is. By inputting your data into the VAR function, you can easily calculate this value and gain deeper insights into your dataset.

Documentation

Estimates the variance based on a sample.

Syntax

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

Parameter	Description
`number1`	The first number or range of numbers that you want to calculate the variance of. At least one number is required.
`numberN`	Optional. 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 function is used to calculate the variance of a sample dataset. Variance is a statistical measurement of the spread between numbers in a data set.

Empty cells: The VAR function ignores empty cells in the dataset.
Text: If the dataset contains text, the VAR function will ignore these cells.
Booleans: The VAR function will interpret TRUE as 1 and FALSE as 0.
Errors: If the dataset contains cells with error values, the VAR function will return an error.

Common Errors

Error	Description
#VALUE!	This error occurs when the provided arguments are non-numeric.
#DIV/0!	This error is returned when there is only one number in the dataset. Variance requires at least two numbers to be calculated.

Best practices

Make sure all the cells you are including in the function contain numeric values. Non-numeric values can cause errors.

Be aware that VAR function treats TRUE as 1 and FALSE as 0. If you do not want this conversion, you may need to modify your data.

Use VAR function when your data represents a sample of a population. If your data represents the entire population, use VARP function instead.

Always check your dataset for error values before using the VAR function, as it will return an error if there are any.

Usage

A few examples using the VAR function.

VAR(1,2,3,4,5)  
// returns variance of numbers 1 through 5

VAR(A1:A10)  
// returns the variance of values in cells A1 through A10

VAR(B1:B10, C1:C10)  
// returns the variance of the combined sets of values

VAR(TRUE, FALSE, 1, 0)  
// treats TRUE as 1 and FALSE as 0, returns variance of [1,0,1,0]

VAR(10, , 20)  
// ignores empty cells, returns variance of {10,20}
