To find the median, we need to arrange the data set in order from least to greatest: 55, 60, 62, 67, 70, 72, 75, 76, 77, 85, 95. The median is the middle number, which is 72 in this case. Therefore, the correct answer is D. Option A is incorrect because it suggests the median cannot be found, but it can be found for interval-ratio scores. Option B and C are incorrect because they are not the middle numbers in the ordered data set.
