- 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.
