The median number of books read during the summer by Class 1
is .
The median number of books read during the summer by Class 2
is .
Class has a higher median number of books read during the
summer.
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:
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
Now we find the median for each class. Since there is an odd number of data points in each class, the median is simply the middle number.
For Class 1, the median is the 8th number in the list, which is 5.
For Class 2, the median is the 8th number in the list, which is also 3.
Therefore, Class 1 has a higher median number of books read during the summer.
