VARA function

PRO BASIC

The VARA function in Jspreadsheet Formulas Pro is a tool that estimates the variance in a sample of data. This data can include numbers, text, and logical values, making it versatile for different types of data analysis. Essentially, it measures how much the data points in your sample differ from the average value of the sample. It's a useful tool in statistical analysis when you need to understand the spread or variability of your data.

Documentation

Estimates the variance based on a sample, including numbers, text, and logical values.

Syntax

VARA(value1, [value2], ...)

Parameter	Description
`value1`	The first value or range of values that you want to calculate the variance of. At least one value is required.
`[valueN]`	Additional values or ranges of values that you want to include in the calculation. You can include up to 255 values or ranges. The values can be numbers, text, or logical values (TRUE or FALSE).

Behavior

The VARA function is used to estimate the variance of a sample, including text and logical values. It calculates and returns the variance based on a sample.

If the data set includes logical values or text representations of numbers, VARA includes them in the calculation whereas the regular VAR function would ignore them.
If the data set includes text that cannot be translated into numbers, VARA interprets them as zeroes.
If the data set includes logical values, VARA translates TRUE as 1 and FALSE as 0.
If a cell in the reference or range is an empty cell, VARA ignores it.
If the data set includes error values, VARA returns an error.

Common Errors

Error	Description
#DIV/0!	This error occurs when the data set only contains one number or an empty cell. Variance requires at least two numbers to be calculated.
#VALUE!	This error occurs when the function is used incorrectly. For example, including a string of text as an argument that doesn't represent a logical value or number.
#N/A	This error occurs when some cells in the range are not available or do not exist.

Best practices

Always ensure the data set contains at least two numbers to avoid the #DIV/0! error.

Be aware that VARA interprets text and logical values differently than other statistical functions. It might be more appropriate to use VAR if your data set includes these types of values and you want to ignore them.

Keep in mind that VARA treats logical values and number-stored-as-text differently than VAR. Make sure you are using the function that best suits your data.

Usage

A few examples using the VARA function.

VARA(1, 2, 3, 4, 5)  
// returns variance of the numbers 1–5

VARA(A1:A10)  
// returns variance of values in A1:A10, including text ("5") and logicals (TRUE/FALSE)

VARA(B1:B10, C1:C10)  
// returns variance of combined values across both ranges

VARA(TRUE, FALSE, 1, "2")  
// treats TRUE as 1, FALSE as 0, "2" as 2 → calculates variance of [1,0,1,2]

VARA("hello", 10, 20)  
// "hello" is non-numeric text → treated as 0, calculates variance of [0,10,20]
