- The characteristic values are shown as a number,
- for the numerical values there is a natural zero point and
- the unit of measurement is of course given (i.e. “ piece ” in the broadest sense ). So it is a natural unit .
Example: For the characteristic “population size of a country”, the number of inhabitants is the natural measure with the natural zero point “no inhabitants”.
With absolute scales, the scale unit cannot be freely selected. Absolute scales are clearly defined and scale transformations are not permitted.
