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
