           5   8    3    5      4     2    1

      Start by writing the data in numerical order. 1, 2, 3, 4, 5, 5, 8
      range: 8 – 1 = 7       Subtract least value from greatest value.
      mean: 1 + 2 + 3 + 4 + 5 + 5 + 8 = 28        Add all values.
               28 ÷ 7 = 4     Divide the sum by the number of items.
      median: 4 There are an odd number of items, find the middle value.
      mode: 5       5 occurs most often.

      The range is 7 in.; the mean is 4 in.; the median is 4 in.; and the
      mode is 5 in.
