Answer

Answer:

median and IQR

Explanation:

Step1: Check data distribution

Box - plots suggest non - normal distribution.

Step2: Recall measure properties

Mean is affected by outliers, median is robust.

Step3: Recall variability measure

MAD is less robust than IQR for non - normal data. IQR is better for skewed data. So median and IQR are best for comparing the two data sets.
