PERCENTILEX.INC
Applies to: 
Calculated column
Calculated table
Measure
Visual calculation
Returns the percentile number of an expression evaluated for each row in a table.
To return the percentile of numbers in a column, use PERCENTILE.INC.
Syntax
PERCENTILEX.INC(<table>, <expression>;, k)
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. |
| k | The desired percentile value in the range 0 to 1 inclusive. |
Return value
The percentile number of an expression evaluated for each row in a table.
Remarks
If k is zero or blank, percentile rank of 1/(n - 1) returns the smallest value. If zero, it is out of range and an error is returned.
If k is nonnumeric or outside the range 0 to 1, an error is returned.
If k is not a multiple of 1/(n - 1), PERCENTILEX.EXC will interpolate to determine the value at the k-th percentile.
PERCENTILEX.INC will interpolate when the value for the specified percentile is between two values in the array. If it cannot interpolate for the k percentile specified, an error is returned.
This function is not supported for use in DirectQuery mode when used in calculated columns or row-level security (RLS) rules.
