The median of a list of data is the middle item in that data when it has been arranged in order of size.
If the list contains an even quantity of data, then the median is the mean average of the middle two values.

For example
the median of the five numbers 3,8,12,13,19 is 12
the median of the five numbers 6,2,9,1,3 is 3 not 9.
the median of the size numbers 1,4,7,9,10,16 is 8, being the mean average of the two middle numbers 7 and 9.
