median is the middle, m = m is how i remember it.
first put the numbers in order...
4, 4, 4, 6, 7, 7, 9, 9,
mark the numbers off, then the middle number is the median.
if there is an even amount of numbers, you still just find the middle.
the middle of 6 and 7 would be 6.5, so...
the median is 6.5 !
