Answer 1

Given the data sets:

A: 21,963,20,786, 21,202, 22,251, 21,848, 20,431, 20,336, 22,017, 20,119, 21,984, 20,261, 20,570, 20,855, 21,971

B: 86, 74, 92, 73, 74, 83, 80, 91, 76, 99, 72

The coefficient of variation indicates how spread out the data of a sample or population are; hence:

CV for Data Set A = 127.9%

CV for Data Set B = 11.2 %
