To find the median, we first need to arrange the data in each class in ascending order:
Class 1: 0, 1, 1, 3, 4, 4, 5, 5, 5, 6, 6, 6, 7, 8, 10
Class 2: 0, 0, 1, 2, 2, 2, 3, 3, 4, 5, 6, 6, 7, 9, 10
Since each class has 15 students, the median will be the average of the 8th and 9th numbers in the ordered list.
For Class 1:
Median = (5 + 6) / 2 = 5.5
For Class 2:
Median = (3 + 4) / 2 = 3.5
Therefore, the median number of books read during the summer by Class 1 is 5.5 and by Class 2 is 3.5.
Class 1 has a higher median number of books read during the summer.
