Median:
The median is the middle value of a set of data when the data is arranged in ascending or descending order. To find the median, we need to arrange the scores in ascending order and determine the middle value.

Arranging the scores in ascending order:
12, 17, 19, 27, 36, 38, 39, 42, 47, 48, 61, 65, 68, 78, 84

Determining the middle value:
Since there are 15 scores, the middle value would be the 8th score when the data is arranged in ascending order.

Median:
The median is 42 (option B) since it is the 8th score when the data is arranged in ascending order.
