Scipy coefficient of variation

Web18 May 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: Web19 Sep 2024 · To find the variance, we just need to divide this result by the number of observations like this: 23.5/6 = 3.916666667 23.5 / 6 = 3.916666667 That's all. The variance of our data is 3.916666667. The variance is difficult to understand and interpret, particularly how strange its units are.
