Calculate the 5 number summary and the interquartile range of the following data: 22, 18, 27, 44, 58, 8, 36, 26 , 10,2, 34, 30,50,68, -43, 38

Q1 =  
Q2 =  
Q3 =  
Min =  
Max =  
IQR =  

There is a potential outlier in this data set
A. True
B. False

Solution

xi

First we ordered data:

xi
-43

18
22
26
27
30

58
68

Finally:

Min = -43
Q1 = 16
Q2 = 28.5
Q3 = 39.5
Max = 68
IQR = Q3-Q1 = 23.5
