The test scores are: 6, 7, 9, 7, 10. 

  • Find the mean.
  • Find the median.
  • Find the mode.
  • Find the range.


  • Hints:
    • Mean: Add all numbers and divide by 5.
    • Median: Order them, pick the middle number.
    • Mode: Which number repeats?
    • Range: Largest – smallest
  • Mean = (6 + 7 + 9 + 7 + 10) ÷ 5 = 39 ÷ 5 = 7.8
  • Median = 7 (numbers in order: 6, 7, 7, 9, 10)
  • Mode = 7
  • Range = 10 – 6 = 4
