What is the range of the scores 10, 15, 22, 9?

• A. 13
• B. 10
• C. 5
• D. 22

Answer: (A)

The range of a set of numbers is calculated by subtracting the smallest value from the largest value in the set. In this case, the scores provided are 10, 15, 22, and 9. First, identify the smallest and largest numbers: - The smallest number is 9. - The largest number is 22. To find the range, you subtract the smallest number from the largest number: 22 - 9 = 13. This calculation shows that the range of the scores is indeed 13. Understanding the concept of range is essential in statistics because it gives an indication of the spread of a dataset, showing how much variation there is between the lowest and highest values. This is why the correct answer is 13.
