Which systems are used to denate quantitative meaning ?

Some systems used to denote quantitative meaning include:

1. Numerical systems (e.g. Arabic numerals, Roman numerals)
2. Measurement systems (e.g. metric system, imperial system)
3. Statistical systems (e.g. mean, median, mode)
4. Mathematical systems (e.g. algebraic equations, geometric formulas)
5. Data representation systems (e.g. bar graphs, pie charts)
6. Financial systems (e.g. currency symbols, accounting methods)

- Ordinal systems assign symbols to objects in such a way that the symbols represent the relative position of the objects on some dimension. For example, the ordinal system of numbers assigns the symbols 1, 2, 3, 4, and 5 to represent the relative positions of five objects on the dimension of height.
- Interval systems assign symbols to objects in such a way that the symbols represent the distance between the objects on some dimension. For example, the interval system of temperature assigns the symbols 0 degrees Celsius, 25 degrees Celsius, and 50 degrees Celsius to represent the distances between three objects on the dimension of temperature.
- Ratio systems assign symbols to objects in such a way that the symbols represent the ratio of the objects on some dimension. For example, the ratio system of weight assigns the symbols 1 pound, 2 pounds, and 3 pounds to represent the ratios of three objects on the dimension of weight.
