# VARA

Spread for WinForms provides advanced software components that support Excel import/export, full cell customization, an extensive calculation engine with over 450 functions and more, all with zero dependencies on Excel.

## Content



This function returns the variance based on a sample of a population, which includes numeric, logical, or text values.

## Syntax

VARA(*value1*,*value2*,...)
VARA(*array*)
VARA(*array1*,*array2*,...)

## Remarks

Each argument can be a double-precision floating-point value, an integer value, text, a logical value, or an array (cell range) of these. Up to 255 arguments may be included. You can use a single array (cell range) instead of a list of values. You can use multiple arrays (cell ranges) as well.

## Remarks

The variance returns how spread out a set of data is.
This function uses the following equation to calculate the variance, where *n* is the number of values.

where x is the value and n is the number of values.
This function assumes that its arguments are a sample of the population. If your data represents the entire population, then compute the variance using the [VARPA](/spreadnet/docs/latest/online-formula/formulas-functionsall/formulas-functsTtoZ/FunctionVARPA) function.
This function differs from [VAR](/spreadnet/docs/latest/online-formula/formulas-functionsall/formulas-functsTtoZ/FunctionVAR) because it accepts text and logical values as well as numeric values.

## Data Types

Accepts numeric, logical, and text data for all arguments. Returns numeric data.

## Examples

`VARA(B3,C4,B2,D10,E5)`
`VARA(A1:A9)`
`VARA(R1C2,100,R2C5,102)`
`VARA(R1C1:R9C1)`
`VARA(R1C1:R1C9)`
`VARA(98,85,76,87,92,89,90)` gives the result 45.8095238095

## Version Available

This function is available in product version 2.0 or later.
