Answer
Explanation:
Step1: Recall inter - quartile range formula
$IQR = Q_3 - Q_1$, where $Q_1$ is the first quartile and $Q_3$ is the third quartile.
Step2: For Jefferson Middle School
From the box - and - whisker plot, $Q_1 = 4$, $Q_3 = 8$. Then $IQR_{Jefferson}=8 - 4=4$.
Step3: For West Side Middle School
From the box - and - whisker plot, $Q_1 = 3$, $Q_3 = 7$. Then $IQR_{WestSide}=7 - 3 = 4$.
Step4: Compare variabilities
Since $IQR_{Jefferson}=4$ and $IQR_{WestSide}=4$, the variabilities in the middle 50 percent are the same.
