Returns the variance of the entire population.
Syntax
VAR.P()
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 the entire population.
Remarks
VAR.P assumes that the column refers the entire population. If your data represents a sample of the population, then compute the variance by using VAR.S.
VAR.P uses the following formula:
∑(x - x̃)2/n
where x̃ is the average value of x for the entire population
and n is the population size
Blank rows are filtered out from
columnNameand not considered in the calculations.An error is returned if
columnNamecontains 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 estimates the variance of the SalesAmount_USD column from the InternetSales_USD table, for the entire population.
= VAR.P(InternetSales_USD[SalesAmount_USD])
