(d1) thre is no outlier
inter quartile range is calcuated (IQR), using first quartile Q1 and third quartile Q3 with the help of ms-excel
observation below Q1-1.5*IQR=117-1.5*445=-550.5 and above Q3+ 1.5*IQR=562+1.5*445=1229.5 , will be outlier.
since no-observations are outside this range (-550,1230) , so thre is no outlier
(d2) limitrs of outlier are ( -550,1230)
Q1= 117 Q3= 562 IQR=Q3-Q1= 562-117= 445Related Questions
