1·5% the coefficient of variation.
we can calculate the coefficient of variation by using the Following Formula.
coefficient of variation = Standard deviation Mean x 100
where standard deviation and mean are already given. standard deviation = 18% Mean or Arithmetic Mean = 12% Here standard deviation and Arithmetic means are already. given in percentage value.
So, Coefficient of variation: = Standard deviation/Mean
= 18/12
= 1·5%.
The coefficient of variation (CV) is the ratio of the standard deviation to the mean. The higher the coefficient of variation, the greater the spread around the mean. Commonly expressed as a percentage. The formula for coefficient of variation is coefficient of variation = (standard deviation / mean) * 100.
