PERCENTILEX.EXC DAX Function (Statistical)
Returns the k-th (exclusive) percentile of an expression values in a table.
Syntax
| Parameter | Attributes | Description |
|---|---|---|
|
Table Iterator |
Table over which the Expression will be evaluated. |
|
|
Expression Row Context By Expression |
Expression to evaluate for each row of the table. |
|
| K |
Desired percentile value in the interval [1/(n+1),1-1/(n+1)], where n is a number of valid data points. |
Return values
Percentile value.
Remarks
PERCENTILEX.EXC considers the blank values returned by Expression. This behavior is different from PERCENTILE.EXC, which ignores the blank values.

Statistical Patterns
DAX includes a few statistical aggregation functions, such as average, variance, and standard deviation. Other typical statistical calculations require you to write longer DAX expressions. Excel, from this point of view, has a much richer language. The Statistical Patterns are a collection of common statistical calculations: median, mode, moving average, percentile, and quartile. » Read more
