deprecated class %ZEN.Report.Aggregate.Median extends %ZEN.Report.CustomAggregate

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.
