Answer 1

The mean is the average of the scores while the range is the difference between the highest and lowest scores.

Mean is a measure of central tendency.

Range measures variability of the data. Looking at the range in each scenario, class D has the highest range. Thus, it has the most variability. Correct answer is class D
