Question

The standard deviation and the mean of 16 values are 15.6 and 20.5. What is the coefficient of variation ?​

Answer 1

Answer:

CV = coefficient of variation = 0.761

Step-by-step explanation:

The coefficient of variation is defined as the standard deviation divided by the mean of a population, which in this case,

standard deviation = 15.6

mean = 20.5

CV = coefficient of variation = 15.6/20.5 = 0.761

Note that if the 16 values form a sample (i.e. not the entire population), the above result is an estimate of the CV.
