Answer:
To answer this item, we add up all the scores and divide the sum by the total number of quizzes.
0: 0 quizzes
1 : 1 quiz total : 1
2: 3 quizzes total : 6
3: 4 quizzes total : 12
4: 4 quizzes total : 16
5: 1 quiz total : 1
There are 13 quizzes and the total score is 36. Dividing the total score by the total number of quizzes will give us a final answer of 2.77.
