Looking at the stem-and-leaf display, the majority of the students scored in the 70s and 80s. The middle value of the data set (the median) is the 15th value when the scores are listed in order from smallest to largest. This value is 80, which falls within the range of the answer choices. However, it is clear from the display that there are some scores above 80, so the best choice is D) 80.5, which is the closest value to the median in the list of answer choices.
