Consider the following two data sets of five observations each:
Data Set A: 15, 16, 17, 18, 80
Data Set B: 20, 22, 24, 26, 28
(i) Calculate the range for each data set.
(ii) Calculate the standard deviation for each data set, correct to one decimal place.
(iii) Which measure—range or standard deviation—gives a fairer comparison of variability between the two data sets? Justify your answer in one sentence.
