A student scored 65, 71, 78, 62, 94 on five quizzes. What is the mean score?
Answer and explanation
Correct answer: D. 74
- Step 1: The sum is 370. Step 2. 370 / 5 = 74. Answer: 74. Why not the others: 71: this is the median, the middle score, not the mean. 370: this is the total; it was not divided by 5. 94: this is the highest score.
