In conclusion, one notes that among these indices of variability each
one characterizes a particular aspect of the arrangement of the properties in
the neighborhood or then express this in a relative or absolute way. These indices
are particularly adapted to a nominal level of measurement because they consider
neither the hierarchy of the values nor their intervals.
