Fifteen students are randomly selected from two different classes. They were asked how many books they read during the
summer. Their responses are as follows. Find the median number of books read by each class. Which class has a higher
median number of books read?
Class 1: 0, 5, 3, 6, 7, 8, 10, 1, 1, 4, 5, 6, 4, 5, 6
Class 2: 2, 2, 4, 3, 0, 0, 6, 7, 10, 9, 6, 5, 3, 1, 2
To find the median number of books read by each class, we first need to arrange the data in ascending order.
For Class 1:
0, 1, 1, 3, 4, 4, 5, 5, 5, 6, 6, 6, 7, 8, 10
Since there is an odd number of values (15), the median is the middle value, which is the 8th value in this case.
So, the median number of books read by Class 1 is 5.
For Class 2:
0, 0, 1, 2, 2, 2, 3, 3, 4, 5, 6, 6, 7, 9, 10
Again, since there is an odd number of values (15), the median is the middle value, which is the 8th value in this case.
So, the median number of books read by Class 2 is 3.
Therefore, Class 1 has a higher median number of books read compared to Class 2.
