The coefficient of variation (CV) is a statistical measure that represents the relative variability of a dataset. It is expressed as a percentage and provides insights into the dispersion or spread of data points to the mean. CV is a dimensionless number, making it valuable for comparing the variability of different datasets, especially when they have different scales or units. In essence, the CV helps you understand the stability and consistency of data. A low CV indicates that the data points are closely clustered around the mean, suggesting greater precision and reliability. Conversely, a high CV suggests greater variability, showing potential fluctuations or uncertainties in the dataset.
