Answer
Explanation:
Step1: Recall IQR definition
IQR = Q3 - Q1, where Q3 is third - quartile and Q1 is first - quartile. In a box - and - whisker plot, the length of the box represents the IQR.
Step2: Observe box lengths
By looking at the box - and - whisker plot, we can see that the box for married males has the shortest length among the four groups (single males, single females, married females, married males).
Answer:
married males
