If you take 5 quizzes and get scores of 95%, 95%, 80%, 85%, and 75%, how would you find your mean quiz score? A
Find the score that is in the middle.

B
Add all the scores together and divide by the number of scores.

C
Add 95 + 80 + 85 + 75 together and divide by 4.

D
Identify the quiz score that appears most often.

The answer is C.

Step-by-step explanation:

Remember, to find the mean of some scores, you must add all the scores together, then you must divide by the number of scores you added. In this case, you would divide by four, because you had four numbers you added to gether.
