The solution to this particular problem says you have to average the 8 and the 9 in the lower half of the spread (getting 8.5). I don't think you do since there are 7 numbers before the median of 10 (7,8,8,8,9,9,10). This means that you'd just pick 8 as the lower half median. Remember, there are two 10's and it's the second 10 that is the overall median which is why I have one 10 in my lower set.
