a type of average, the data set is rearranged in numerical order and the middle value obtained, typically by counting in from either end of the sequence. If two "middle" values remain, then the ''mean'' average of these two numbers ( (x+y)/2 ) is found to give the ''median'' value of the set. | a type of average, the data set is rearranged in numerical order and the middle value obtained, typically by counting in from either end of the sequence.
