The median is the middle score when all scores are arranged in ascending order. Given there are 10 scores in the 45-49 interval, 30 scores above, and 26 below, the total number of scores is 66. The median would fall within the 45-49 interval because the 33rd and 34th scores (the middle scores for an even number of total scores) would be within the 10 scores of the 45-49 interval, not at the specific values of 10, 26, 45, or 49.
