The data shows a number of miles ran per week by randomly selected students from two different classes period finally different between the medians which class has a higher medium by how much

To determine which class has a higher median and by how much, we need to first calculate the median number of miles ran per week for each class. The median is the middle value when the data points are arranged in order. If there is an even number of data points, the median is the average of the two middle values.

Let's say we have the following data for the number of miles ran per week for each class:

Class 1: 10, 15, 20, 25, 30
Class 2: 5, 10, 15, 20, 25, 30

For Class 1:
The median is the middle value, which is 20.

For Class 2:
The median is the average of the two middle values, which are 15 and 20.
Median = (15 + 20) / 2 = 17.5

Therefore, Class 1 has a higher median number of miles ran per week by 2.5 miles.
