Is the median not what you were expecting? You also didn't show what
numbers you entered at the prompt. However, when I run this i get the
correct avg, but the % operator you used won't return the median.
Instead you getting the value of the remainder of your division i.e.
6%2=0 , and 7%2=1. If you want the middle value just find the length of
the list and divide by two. But if the length isn't a even number
you'll have to find the avg of the two middle values. Hope that
helps.......Chris
