A student scored 84, 94, 77, 98, 62 on five quizzes. What is the mean score?
Answer and explanation
Correct answer: A. 83
- Step 1: The sum is 415. Step 2. 415 / 5 = 83. Answer: 83. Why not the others: 84: this is the median, the middle score, not the mean. 415: this is the total; it was not divided by 5. 98: this is the highest score.
