GEOMEANX
Applies to: 
Calculated column
Calculated table
Measure
Visual calculation
Returns the geometric mean of an expression evaluated for each row in a table.
To return the geometric mean of the numbers in a column, use GEOMEAN function.
Syntax
GEOMEANX(<table>, <expression>)
Parameters
| Term | Definition |
|---|---|
| table | The table containing the rows for which the expression will be evaluated. |
| expression | The expression to be evaluated for each row of the table. |
Return value
A decimal number.
Remarks
The GEOMEANX function takes as its first argument a table, or an expression that returns a table. The second argument is a column that contains the numbers for which you want to compute the geometric mean, or an expression that evaluates to a column.
Only the numbers in the column are counted. Blanks, logical values, and text are ignored.
This function is not supported for use in DirectQuery mode when used in calculated columns or row-level security (RLS) rules.
Example
The following computes the geometric mean of the ReturnPct column in the Investments table:
= GEOMEANX( Investments, Investments[ReturnPct] + 1 )
