Range is the most basic measure of variability because it simply represents the difference between the highest and lowest values in a data set. It does not take into account the distribution of the rest of the data and can be affected by outliers, but it is still a useful quick calculation to get a sense of the spread of the data. The other options (median, average deviation, and standard deviation) are more complex measures of variability that take into account the distribution of the data and the distance of individual observations from the center.
