VAR.S
Applies to:
Calculated column
Calculated table
Measure
Visual calculation
Returns the variance of a sample population.
Syntax
VAR.S(<columnName>)
Parameters
Term | Definition |
---|---|
columnName | The name of an existing column using standard DAX syntax, usually fully qualified. It cannot be an expression. |
Return value
A number with the variance of a sample population.
Remarks
VAR.S assumes that the column refers to a sample of the population. If your data represents the entire population, then compute the variance by using VAR.P.
VAR.S uses the following formula:
∑(x - x̃)2/(n-1)
where x̃ is the average value of x for the sample population
and n is the population size
Blank rows are filtered out from columnName and not considered in the calculations.
An error is returned if columnName contains less than 2 non-blank rows.
This function is not supported for use in DirectQuery mode when used in calculated columns or row-level security (RLS) rules.
Example
The following example shows the formula for a measure that calculates the variance of the SalesAmount_USD column from the InternetSales_USD for a sample population.
= VAR.S(InternetSales_USD[SalesAmount_USD])
