Question

The results from the last quiz that Mr. Tham gave his class are 10, 15, 25, 75, 75, 77, 80, 83, 85, and 90. If he wants to persuade his class to study harder for the next quiz, what statistical measure should he use? Answer: C. mean (The class average will be higher) why?

Answer 1

The mode is 75, the median is 76 and the mean is 61.5. He should tell the students about the mean because it's the lowest statistical measure, and they'll probably try harder next time to improve it.
