Chapter 3, Section 3.5, Problem 092a

Calculate the values of the three quartiles and the interquartile range.

arranging the data in ascending order we get

51,52,53,54,54,55,56,56,57,57,58,58,58,59,60,61,61,62,62,62,63,63,64,66

upper Q1 is that value under which 1/4th of values exist

so Q1=55.5

upper Q2 is that value under which 1/2th of values exist

so Q2=58

upper Q3 is that value under which 3/4th of values exist

so Q3=62

so IQR=Q3-Q1=6.5
