PERCENTILE.EXC DAX Function (Statistical)

Returns the k-th (exclusive) percentile of values in a column.

Syntax

PERCENTILE.EXC ( <Column>, <K> )
Parameter Attributes Description
Column

A column containing the values.

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

Scalar A single variant value.

Percentile value.

Remarks

PERCENTILEX.EXC considers the blank values returned by Expression. This behavior is different from PERCENTILE.EXC, which ignores the blank values.

Examples

--  PERCENTILE.EXC computed the k-th percentile, exclusive
--  PERCENTILE.INC computed the k-th percentile, inclusive
--
--  Both functions rank the N values from 1 (lowest)
--  to N (highest), then determine the possibly-non-integer 
--  calculated rank for the specified percentage argument K 
--  (a decimal number between 0.00 and 1.00), and finally 
--  use linear interpolation between the closest integer-rank 
--  values of the data array.
--
--  For PERCENTILE.EXC the calculated rank is K*(N+1)
--  For PERCENTILE.INC the calculated rank is K*(N-1)+1
--
--  MEDIAN corresponds to PERCENTILE.INC with k=0.50

  • 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
