Consider the following two sample data sets.

Set 1:	13	26	18	23	22
Set 2:	3	8	3	7	8

a. Calculate the coefficient of variation for each data set.

b. Which data set has less consistency (or more variability)?

a. The coefficient of variation for data set 1 is ?

(Round to one decimal place as needed.)

The coefficient of variation for data set 2 is ?

(Round to one decimal place as needed.)

b. Which data set has less consistency (or more variability)? Choose the correct answer below.

A.

Data

set1

has less consistency (or more variability) because its coefficient of variation is greater.

B.

Data

set1

has less consistency (or more variability) because its coefficient of variation is less.

C.

Data

set2

has less consistency (or more variability) because its coefficient of variation is greater.

D.

Data

set2

has less consistency (or more variability) because its coefficient of variation is less.
