The data shows the number of miles run per week by randomly selected students from two different classes. Find the difference between the medians. Which class has a higher median? By how much?
Class 1: 6, 8, 10, 11, 14, 4, 5, 8, 2, 7, 7, 5, 10, 12, 11
Class 2: 6, 4, 5, 6, 7, 8, 12, 9, 10, 11, 5, 8, 7, 4, 10

Class 2 has a higher median than Class 1 by 1 mile.
Class 1 has a higher median than Class 2 by 0.5 mile.
Class 1 has a higher median than Class 2 by 1 mile.
Class 2 has a higher median than Class 1 by 0.5 mile.
To find the median for each class, we first need to order the data points:
Class 1: 2, 4, 5, 5, 6, 7, 7, 8, 8, 10, 10, 11, 11, 12, 14
Median for Class 1 = 8
Class 2: 4, 4, 5, 5, 6, 6, 7, 7, 8, 8, 9, 10, 10, 11, 12
Median for Class 2 = 7
The difference between the medians is 8 - 7 = 1 mile. Therefore, Class 1 has a higher median than Class 2 by 1 mile.
