|Definition||Quantity, defined by a conventional measurement procedure for which a total ordering relation can be established, according to magnitude, with other quantities of the same kind, but for which no algebraic operations among those quantities exist|
|Scope||An ordinal scale serves for the comparison of examined values regarding a kind-of-property that can be ordered by magnitude.|
Quantities with results that are expressed in an ordered rank.
A given result can be “lower” or “greater” than another result for the same quantity.
If results are given as numerical values, they cannot be added, subtracted, divided or multiplied.
The difference between two values is not the same between the numerical values.
Note 1: Ordinal scale is attributed to NPU codes with arbitrary kinds-of-quantity.
Note 2: Results have no ISQ dimensions or SI units
The results are presented with alphabetic letters or numerical values in a hierarchal way.
