To find the median, we need to arrange the numbers in each class in ascending order:
Class 1: 2, 4, 5, 5, 6, 7, 7, 8, 8, 10, 10, 11, 11, 12, 14
Class 2: 4, 4, 5, 6, 6, 7, 7, 8, 8, 9, 10, 10, 11, 12
The medians for each class are the middle values of the arranged numbers:
Class 1 median: 8
Class 2 median: 8
The difference in medians is 8 - 8 = 0.
Therefore, the correct answer is:
• Class 1 and Class 2 have the same median.
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 (1 point)
• Class 1 has a higher median than Class 2 by 1 mile.
• Class 1 has a higher median than Class 2 by 0.5 mile.
• Class 2 has a higher median than Class 1 by 0.5 mile.
• Class 2 has a higher median than Class 1 by 1 mile.
