@MEDIAN

Returns the median (the middle number) of the specified data set (expList). Half the numbers in the data set are larger than the median, and half are smaller.

Syntax

@MEDIAN (SKIPNONE | SKIPMISSING | SKIPZERO | SKIPBOTH, expList)

Parameter	Description
SKIPNONE	Includes all cells specified in expList, regardless of their content, during calculation of the median.
SKIPMISSING	Excludes all #MISSING values from expList during calculation of the median.
SKIPZERO	Excludes all zero (0) values from expList during calculation of the median.
SKIPBOTH	Excludes all zero (0) values and #MISSING values from expList during calculation of the median.
expList	Comma-delimited list of member specifications, variable names, functions, or numeric expressions. expList provides a list of numeric values across which the median is calculated.

Notes

If the member you are calculating and expList are not in the same dimension, use the @RANGE function to cross the member with the list of members (for example, to cross Sales with the children of 100).
@MEDIAN sorts expList in ascending order before calculating the median.
When expList contains an even number of values, the @MEDIAN function calculates the average of the two middle numbers.
@MEDIAN treats #MISSING values as 0 unless SKIPMISSING or SKIPBOTH is specified.
When you use @MEDIAN in a calculation script, use it within a FIX statement. Although FIX is not required, using it may improve calculation performance.
When you use @MEDIAN across a large range in a sparse dimension, you may need to increase the size of the calculator cache. For more information on the calculator cache, see the Oracle Essbase Database Administrator's Guide.

Example

The following example is based on the Sample Basic database. Assume that the Measures dimension contains an additional member, Median. This example calculates the median sales values for all products and uses the @RANGE function to generate expList:

FIX (Product)
Median = @MEDIAN(SKIPBOTH,@RANGE(Sales,@CHILDREN(Product)));
ENDFIX

This example produces the following report:

                         Jan     New York
                      Actual       Budget
                      ======       ======
Sales    Colas         678          640
         Root Beer     551          530
         Cream Soda    663          510
         Fruit Soda    587          620
         Diet Drinks   #MI          #MI
          Product     2479         2300

Median   Product       625          575

Because SKIPBOTH is specified in the calculation script, the #MI values for Diet Drinks are skipped. The remaining four products create an even-numbered data set. So, to calculate Median->Product->Actual, the two middle numbers in the set (587 and 663) are averaged to create the median (625). To calculate Median->Product->Budget, the two middle numbers in the set (530 and 620) are averaged to create the median (575).
