To find the median number of books read by each class, we first need to arrange the responses in ascending order.
For Class 1:
0, 1, 1, 3, 4, 4, 5, 5, 5, 6, 6, 6, 7, 8, 10
Since there are 15 responses, the median for Class 1 is the middle value, which is the 8th value in the list: 5.
For Class 2:
0, 0, 1, 2, 2, 2, 3, 3, 4, 5, 6, 6, 7, 9, 10
Again, the median for Class 2 is the middle value, which is the 8th value in the list: 3.
Therefore, the median number of books read by Class 1 is 5 and the median number of books read by Class 2 is 3. Thus, Class 1 has a higher median number of books read during the summer.
