The coefficient of variation is the ratio of the standard deviation to the mean, expressed as a percentage. It is used to compare the variability of datasets with different means, and it is a unitless measure of relative variability. The interquartile range measures the spread of the middle 50% of the data and is not a ratio. The variance and standard deviation measure the spread of the data, but not in relation to the mean.
