Statistical calculations

Question

Is there any built in library that I can use for calculating median in java??

I was working with apache.commons.math for other statistical functions but median was nowhere to be found.

Thank you,

Answer 1

Put all the numbers into a list, sort the list, and take the middle value (or the average of the two middle values for even size). No calculations necessary

Answer 2

Which version of Apache Commmons Math are you using? There is a median class at least in 2.1 onwards (older version i am not sure). You can use it as:

Median median = new Median();
median.evaluate(values);
