The median is the middle value when all the numbers in a set are arranged in ascending or descending order. Therefore, the median of {2,5,8,9,12,13} is the middle value, which is 9. Option A is incorrect because it is the mean (average) of the set and not the median. Option C and D are incorrect because they do not fall in the middle of the set when arranged in ascending order.
