Coefficient of variation measure the consistency of a dataset relative to the mean. The dataset with the largest coefficient of variation has the greatest variation (less consistent), so that, dataset that has smaller cv is more consistent. a) Develop ONE R programming function named "Coeff" to determine the coefficient of variation for ONE dataset by using the following formula.
