This is not true "for some sets" as {0, 1} , but for ANY numerical set which has an even cardinality (I mean 2 i , i=1,2,...).
In such a case, it is just an assumption that the MEDIAN is defined as the average of the 2 "central" terms (according to the current comparer).
[another point where median is defined actually as an average]
