Detailed Description

Aggregate for the median of a set of numerical data.

The median is a number with half of the data set of greater value than it, and half of lesser value. For a data set with an odd size, the median is a member of the data set. For a data set with an even size, the median is half-way between two members of the data set.

Member Function Documentation

◆ GetResult()

_.Library.String GetResult ( )

Returns the median.

Returns "" for an empty data set.

Uses a divide and conquer selection algorithm.

Reimplemented from CustomAggregate.
