WebMay 18, 2024 · One way to determine if a standard deviation is “low” is to compare it to the mean of the dataset. 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 = s / x where: s: The standard deviation of dataset x: The mean of dataset
