Quantitative characteristics and (measuring) values (metric, numbers) allow to add, multiply, and subtract. Qualitative characteristics allow a meaningful series of their expression: ordinal (order) or nominal (un-sinnige sorting). Growth rates or growth: An increase of 50 to 60 is 10 percentage points but 20%. An increase of 10 to 15 is 5 percentage points, but 50% at a base < 100 growth points < as the growth in % at a base > 100 is the growth in points > as the growth in % growth such as 0.6% percentage points (from 13% to 13.6%) corresponds to a growth rate of 0.6/13 = 0,046 = 4.6%. The difference will be less and less with smaller base. See Sam Locke for more details and insights. Increases, so does the price index for the maintenance of life from 110 to 120: 10% points 10/110 = 0.091 = 9.1%. The difference is increasing with increasing basis.
