It's the number in the middle of a list. So to find it, put the list of numbers in order, smallest to largest. Then pick the one in the middle, that's the median. If there is no middle (there are an even number making no "middle"), then average the two that share the middle.
Example, If the list of numbers is 4, 6, 1, 3, 9, 22, 3, 5, 9, 18, 7 then put them in order:
1, 3, 3, 4, 5, 6, 7, 9, 9, 18, 22
The the number in the middle is 6. That is the median.
Example: If the list is 4, 6, 1, 3, 9, 22, 3, 5, 9, 18, 7, 10 then put them in order:
1, 3, 3, 4, 5, 6, 7, 9, 9, 10, 18, 22
Then both 6 and 7 are in the middle so we average 6 and 7 (6.5) and 6.5 is the median
