Question

Class 1: 12, 8, 7, 4, 0, 7, 5, 10, 1, 0, 1, 3, 2
Class 2: 2, 3, 5, 6, 10, 7, 10, 9, 2, 2, 3, 6, 4
The median number of video games played during a week by Class 1 is The median number of video games played during a week by Class 2 is -

Answer 1

To find the median, we first need to reorder the data in each class in ascending order:

Class 1: 0, 0, 1, 1, 2, 3, 4, 5, 7, 7, 8, 10, 12
Class 2: 2, 2, 2, 3, 3, 4, 5, 6, 6, 7, 9, 10, 10

Since there are 13 values in each class, the median will be the average of the middle two values. In Class 1, the middle two values are 4 and 5, so the median for Class 1 is (4 + 5) / 2 = 4.5. In Class 2, the middle two values are 5 and 6, so the median for Class 2 is (5 + 6) / 2 = 5.5.

Therefore, the median number of video games played during a week by Class 1 is 4.5 and the median number of video games played during a week by Class 2 is 5.5. Class 2 has a higher median number of video games played in a week.
