Variability
What is the measurement of variability that is most distorted by the presence of outliers?
The range is most distorted.
Advantage and disadvantage of range?
The advantage of range in a set of data is that it provides a simple measure of the spread or dispersion of the values. It is easy to calculate by subtracting the minimum value from the maximum value. However, the disadvantage of range is that it is heavily influenced by outliers, as it only considers the two extreme values and may not accurately represent the variability of the entire dataset. For a more robust measure of dispersion, other statistical measures such as standard deviation or interquartile range may be more appropriate.

collection, diversity, assortment, selection, multiplicity, array, range, mixture, change, variability, variation
How can you represent the variability of a collection of numbers with one number?
