Visual calculation
Returns the standard deviation of a sample population.
Syntax
STDEV.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 that represents the standard deviation of a sample population.
Exceptions
Remarks
STDEV.S assumes that the column refers to a sample of the population. If your data represents the entire population, then compute the standard deviation by using STDEV.P.
STDEV.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
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 calculates the standard deviation of the column, SalesAmount_USD, when the table InternetSales_USD is the sample population.
= STDEV.S(InternetSales_USD[SalesAmount_USD])
