The range is the most general measure of variability as it only considers the difference between the highest and lowest values in a dataset. It is the least useful measure of variability as it is sensitive to outliers and does not provide information about the spread of the rest of the data. The other options (median, standard deviation, and mean deviation) are all more specific measures of variability that provide more information about the distribution of the data.
