moneyman, just be careful when calculating which score is the median score. The formula, so to speak, for finding which score is the median score in a list of n scores is given by (n+1)/2. The median here, out of 73 scores, would be the 37th score, not the average of 36 and 37 (what you'd mean by 36.5th score).
If you don't believe me, just think of smaller examples that you can prove to yourself, like the median of 1, 2, 3, 4, 5 is 3 ((5+1)/2) not 2.5.
It didn't matter in this problem because the "36.5th" score and the 37th score fell in the same interval, but just something to keep your eye on.
