Here, there are 10 numbers, first we have to range the numbers less to greater.

7 ; 8 ; 9 ; 10 ; 11 ; 12 ; 14 ; 15 ; 15 ; 16

[tex]0.25*10=2.5[/tex] so Q1 is the third term. Q1 = 9.

[tex]0.75*10=7.5[/tex] So Q3 is the 8th term. Q3 = 15.

[tex] Q_{3} - Q_{1} = 15-9=6[/tex]

In short, interquartile range of this data set is 6 ( option A) ).

Hope this helps !
