Examples of Median

org.apache.commons.math.stat.descriptive.rank.Median
Returns the median of the available values. This is the same as the 50th percentile. See {@link 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.
