Consider the following sets of sample data:
A: $1.14
, $2.54
, $1.29
, $2.20
, $2.22
, $2.48
, $1.07
, $1.03
, $1.23
, $2.00
, $1.10
, $2.10
, $1.94
, $2.54
B: 4.50
, 4.04
, 3.53
, 4.63
, 3.02
, 3.60
, 4.05
, 4.00
, 4.63
, 4.18
, 4.54
Step 1 of 2 : For each of the above sets of sample data, calculate the coefficient of variation, CV. Round to one decimal place.
A:
Mean = $1.73
Standard deviation = $0.58
CV = (0.58 / 1.73) * 100 = 33.5%
B:
Mean = 4.11
Standard deviation = 0.63
CV = (0.63 / 4.11) * 100 = 15.3%
