Question

A teacher is comparing the test scores of two classes. The range of class 1 is 14, and the interquartile range is 7. The range of class 2 is 12, and the interquartile range is 4.
Which of the following BEST explains which class has greater variability?

A
Class 1 has more variability because there is a smaller difference between the range and interquartile range than class 2.
B
Class 1 has more variability because both the range and interquartile range are greater than class 2, meaning the data is more spread out.
C
Class 2 has more variability because both the range and interquartile range are less than class 1, meaning the data is closer together.
D
Class 2 has more variability because both the range and interquartile range are less than class 1, meaning the data is more spread out.

Answer 1

Class 1 has more variability because both the range and interquartile range are greater than class 2, meaning the data is more spread out.

What is range and interquartile range?

The range is the difference between the largest number and the smallest number in a dataset. The interquartile range is the difference between the first quartile and the third quartile of a dataset.

Range and interquartile range are used to measure the spread of a dataset. The higher range and interquartile range is, the greater the spread and variability of the dataset.
