median


    The median is the middle value, so I'll have to rewrite the list in order:
      13, 13, 13, 13, 14, 14, 16, 18, 21
    There are nine numbers in the list, so the middle one will be the (9 + 1) ÷ 2 = 10 ÷ 2 = 5th number:
      13, 13, 13, 13, 14, 14, 16, 18, 21
    So the median is 14

  1. Good job! I like how you explained your work, but next time, I suggest you make the font a bit bigger.
