## org.apache.commons.math.stat.descriptive.rank
Class Median

    java.lang.Object
      org.apache.commons.math.stat.descriptive.AbstractUnivariateStatistic
          org.apache.commons.math.stat.descriptive.rank.Percentile
              org.apache.commons.math.stat.descriptive.rank.Median

All Implemented Interfaces:
  Serializable, UnivariateStatistic

public class Median
extends Percentile
implements Serializable

Returns the median of the available values. This is the same as the 50th percentile. See `Percentile` for a description of the algorithm used.

Note that this implementation is not synchronized. If multiple threads access an instance of this class concurrently, and at least one of the threads invokes the `increment()` or `clear()` method, it must be synchronized externally.
