[Bug 61071] New: Median calculated incorrectly

https://bz.apache.org/bugzilla/show_bug.cgi?id=61071

            Bug ID: 61071
           Summary: Median calculated incorrectly
           Product: JMeter
           Version: 3.2
          Hardware: PC
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Main
          Assignee: issues@jmeter.apache.org
          Reporter: abalanonline@gmail.com
  Target Milestone: ---

Created attachment 34975
  --> https://bz.apache.org/bugzilla/attachment.cgi?id=34975&action=edit
aggregate report csv file

For even number of tests median should be the mean of the two middle values.
JMeter 3.2 calculate median as 50% line and this is wrong approach.

For example, aggregate report data:
Samples: 2
Min: 197
Max: 252
Average: 224
Median: 197

Here for 2 samples median should be the same as average (224) but it is the
same as min (197) and this is incorrect.

Hi Team,
What shall we do with that ?
It appears it's all a matter of different possible algorithms.

Regards
