Show answer & explanation
Correct answer: B
To understand the calculation of the Coefficient of Variation (CV), we look at how it measures the relative variability of a dataset.
The Coefficient of Variation Formula
The Coefficient of Variation is defined as the ratio of the standard deviation to the mean, expressed as a percentage. It is primarily used to compare the degree of variation from one data series to another, even if the means are drastically different.
The formula is:
CV = (Standard deviation / Mean) × 100
