Question

7. Consider the following sets of sample data:

A:

$29,400, $30,900, $21,000, $33,200, $21,300, $24,600, $29,500, $22,500, $35,200, $20,800, $39,800, $22,300, $35,700, $25,100

B:

4.53, 4.17, 4.48, 3.73, 3.83, 2.91, 2.99, 4.67, 4.21, 4.68, 3.38

Step 1 of 2:

For each of the above sets of sample data, calculate the coefficient of variation, CV. Round to one decimal place.

CV for Data Set A:       %

CV for Data Sat B:        %

Step 2 of 2:

Which of the above sets of sample data has the smaller spread?

Data Set A

Data Set B

Answer 1

Step 1 of 2:

CV for Data Set A: =22.6%

CV for Data Sat B: =16.3%

Step 2 of 2:
