Answer:
4.5.
Explanation:
To find the median of a set of data, we need to first arrange the data in numerical order. Once the data is arranged in order, the median is the middle value in the set. In this case, the data arranged in numerical order is: 2.5, 3.5, 4.5, 5.5, 6.5. The median is the middle value, which is 4.5.
