Infant mortality rates (number of infant deaths, per 1000 live births) are reported by theWorld Bank. In their report for 2010–2014, the five-number summaries (min, Q1, median, Q2, max) were (19, 55, 74, 86, 107) for Africa and (2, 3, 4, 4, 6) for Europe. Sketch side-by-side box plots, and use them to describe differences between the distributions.

(The plot for Europe shows that the quartiles, like the median, are less useful when the data are highly discrete.)
