CHAPTER 24 DataWindow Expression and InfoMaker Functions
Users Guide 707
Return value The numeric datatype of the column. Returns the median of the values of the
rows in range if it succeeds and –1 if an error occurs.
Usage If you specify range, Median returns the median value of column in range. If
you specify DISTINCT,
Median returns the median value of the distinct values
in column, or if you specify expresn, the median of column for each distinct
value of expresn.
For graphs and OLE objects, you do not select the range when you call the
function. The range has already been determined by the Rows setting on the
Data property page (the Range property), and the aggregation function uses
that range.
Argument Description
column The column for which you want the median of the data values.
Column can be the column name or the column number preceded
by a pound sign (#). Column can also be an expression that includes
a reference to the column. The datatype of column must be numeric.
FOR range
(optional)
The data that will be included in the median. For most presentation
styles, values for range are:
• ALL – (Default) The median of all values in column.
• GROUP n – The median of values in column in the specified
group. Specify the keyword GROUP followed by the group
number: for example, GROUP 1.
• PAGE – The median of the values in column on a page.
For Crosstabs, specify CROSSTAB for range:
• CROSSTAB – (Crosstabs only) The median of all values in
column in the crosstab.
For Graph and OLE objects, specify one of the following:
• GRAPH – (Graphs only) The median of values in column in the
range specified for the Rows.
• OBJECT – (OLE objects only) The median of values in column
in the range specified for the Rows option.
DISTINCT
(optional)
Causes
Median to consider only the distinct values in column when
determining the median. For a value of column, the first row found
with the value is used and other rows that have the same value are
ignored.
expresn
(optional)
One or more expressions that you want to evaluate to determine
distinct rows. Expresn can be the name of a column, a function, or
an expression.
