The coefficient of variation (CV) is a measure of the relative variability of a dataset, and it is calculated as the standard deviation divided by the mean, multiplied by 100. If the CV is 0.5, it means that the standard deviation is 50% of the mean, which indicates that the data is highly variable compared to the mean. In general, a CV greater than 1 indicates high variability, while a CV less than 1 indicates low variability.
