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 1

The answer to this problem is not immediately obvious. I'd suggest you actually calculate the mean, the mode and the median. That's relatively easy. Not so easy is making the connection between mean, mode or median to the advisability of studying harder for the next exam. What's your reasoning?

Answer 2

If he wants to persuade the class to study harder he should choose the measure that shows the lowest measure of center.
