8,8^� ,9,9,10,10,11,↓_(median) 11,12,14,15,15,15,15  Q1=9  Q3=15  Semk interquartile range=((Q3−Q1)/2)=3

$$\mathrm{8},\bar {\mathrm{8}},\mathrm{9},\mathrm{9},\mathrm{10},\mathrm{10},\mathrm{11},\underset{\mathrm{median}} {\downarrow}\mathrm{11},\mathrm{12},\mathrm{14},\mathrm{15},\mathrm{15},\mathrm{15},\mathrm{15} \\ $$$$\mathrm{Q1}=\mathrm{9} \\ $$$$\mathrm{Q3}=\mathrm{15} \\ $$$$\mathrm{Semk}\:\mathrm{interquartile}\:\mathrm{range}=\frac{\mathrm{Q3}−\mathrm{Q1}}{\mathrm{2}}=\mathrm{3} \\ $$
