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 ?

Answer 1

Class 1:
15, 20, 25, 30, 35, 40, 45

Class 2:
10, 15, 20, 20, 25, 30, 35, 35

To find the median, we first need to order the data points:

Class 1: 15, 20, 25, 30, 35, 40, 45
Median = 30

Class 2: 10, 15, 20, 20, 25, 30, 35, 35
Median = (20 + 25) / 2 = 22.5

The difference between the medians is: 30 - 22.5 = 7.5

Therefore, Class 1 has a higher median by 7.5 miles.
