  16. 16. 5 7 2 10 3 3 6 Total score: 5 + 7 + 2 + 10 + 3 +
  17. 17. 5 7 2 10 3 3 6 Total score: 5 + 7 + 2 + 10 + 3 + 3 +
  18. 18. 5 7 2 10 3 3 6 Total score: 5 + 7 + 2 + 10 + 3 + 3 +
  19. 19. 5 7 2 10 3 3 6 Total score: 5 + 7 + 2 + 10 + 3 + 3 + 6
  20. 20. 5 7 2 10 3 3 6 Total score: 5 + 7 + 2 + 10 + 3 + 3 + 6 = 36
  21. 21. 5 7 2 10 3 3 6 Total score: 5 + 7 + 2 + 10 + 3 + 3 + 6 = 36 Mean = Total Score The number of scores
  22. 22. 5 7 2 10 3 3 6 Total score: 5 + 7 + 2 + 10 + 3 + 3 + 6 = 36 Mean = Mean = Total Score The number of scores
  23. 23. 5 7 2 10 3 3 6 Total score: 5 + 7 + 2 + 10 + 3 + 3 + 6 = 36 Mean = Mean = Total Score The number of scores
  24. 24. 5 7 2 10 3 3 6 Total score: 5 + 7 + 2 + 10 + 3 + 3 + 6 = 36 Mean = 36 Mean = Total Score The number of scores
  25. 25. 5 7 2 10 3 3 6 Total score: 5 + 7 + 2 + 10 + 3 + 3 + 6 = 36 Mean = 36 7 Mean = Total Score The number of scores
  26. 26. 5 7 2 10 3 3 6 Total score: 5 + 7 + 2 + 10 + 3 + 3 + 6 = 36 Mean = 36 7 There are 7 scores here
  27. 27. 5 7 2 10 3 3 6 Total score: 5 + 7 + 2 + 10 + 3 + 3 + 6 = 36 Mean = 36 7 = 5.1 Our Final Answer!
