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.
