    To find the mean, add the numbers and divide by 9.

    To find the median, find the number in the middle.

  • Algebra -

    Find the mean (average)
    1 + 2 + 4 + 5 + 6 + 8 + 9 + 10 + 10 = sum
    Average = sum/9

    The median is the middle value, 6

    mean - median = postive difference

    Then express this difference as a fraction
