Question

Two groups of students were asked how many pets they had. The table below shows the numbers for each group:

Company A 1 2 1 1 3 5 4 2 3
Company B 3 2 3 2 2 2 1 1 2


Based on the table, which of the following is true?
The interquartile range for Group A students is 0.5 less than the interquartile range for Group B students.
The interquartile range for Group A students is 1.5 more than the interquartile range for Group B students.
The interquartile range for Group A students is equal to the interquartile range for Group B students.
The interquartile range for Group A students is 1 more than the interquartile range for Group B students.

Answer 1

interquartile range for group A = 2.5
interquartile range for group B = 1

2.5 - 1 = 1.5 (to find the difference you subtract)

so the answer is: the interquartile range for group A students is 1.5 more than the interquartile range for group B students.

hope this was helpful!
