WebMay 18, 2024 · A coefficient of variation, often abbreviated CV, is a way to measure how spread out values are in a dataset relative to the mean. It is calculated as: CV = σ / μ where: σ: The standard deviation of dataset μ: The mean of dataset Simply put, the coefficient of variation is the ratio between the standard deviation and the mean. For example: WebThe coefficient of variation (CV) is a measure of relative variability and is calculated as the ratio of the standard deviation to the mean. It is expressed as a percentage. For Project X: CV = (standard deviation / expected value) x 100%. = ($20,000 / $50,000) x 100%. = 40%. Therefore, the answer is (b) 0.40.
