Total Score = 818

27. 4 2 5
5 0 2 4 5 7 7

Total Score = 818
Mean = Total Score
÷
The number of scores

28. 4 2 5
5 0 2 4 5 7 7
6 3 5 6 8
7 0 4
Total Score = 818
Now, count how many
scores there are

29. 4 2 5
5 0 2 4 5 7 7
6 3 5 6 8
7 0 4
Total Score = 818

30. 4 2 5
5 0 2 4 5 7 7
6 3 5 6 8
7 0 4
Total Score = 818
There are 14 scores

31. 4 2 5
5 0 2 4 5 7 7
6 3 5 6 8
7 0 4
Total Score = 818
So the Mean is:

32. 4 2 5
5 0 2 4 5 7 7
6 3 5 6 8
7 0 4
Total Score = 818
So the Mean is:
818 ÷

33. 4 2 5
5 0 2 4 5 7 7
6 3 5 6 8
7 0 4
Total Score = 818
So the Mean is:
818 ÷ 14

34. 4 2 5
5 0 2 4 5 7 7
6 3 5 6 8
7 0 4
Total Score = 818
So the Mean is:
818 ÷ 14 = 58.4
