Calculate the values of the three quartiles and the interquartile range. Where does the value 604 fall in relation to these quartiles? 0 02 The value 604 is in the 7.25 % group from the bottom in the (ranked) data set.Explanation / Answer
puttng above data into ascending order:
Q1 =(n+1)/4 th value =(23/4) th value =5.75 th value =475+0.75*(531-475)=517
Q2 =(n+1)/2 th value =(23/2) th value =11.5 th value =624.5
Q3 =3*(n+1)/4 th value =(3*23/4) th value = th value =17.25 th value=736.5
IQR =Q3-Q1 =219.5
the value 604 is in above 25% ... please provide availbale option
b) 32nd percentile =(n+1)*p= (22+1)*0.32 th value =7.36 th value=572+0.36*(600-572)=582.08
applicants are below this value.
c) % rank for 572 =(7/23)*100 =30.43%
are below 572
