The square root of the variance is the standard deviation, which is a measure of the spread or dispersion of a distribution. The coefficient of variation is the standard deviation divided by the mean, and is useful for comparing the variability of two or more distributions with different units or scales. The interquartile range is a measure of variability that is based on the middle 50% of the data, and is calculated as the difference between the 75th and 25th percentiles. The variance is the average of the squared deviations from the mean, and is also a measure of variability.
