A '''median''' is the middle number in an ordered numerical sequence. if there are two middle numbers, then the median is found by averaging the numbers together.
To use a median as
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.
