I’m not sure which field you mean—“value graduation” can mean different things in different contexts. Briefly, the most common meanings are:
1. Metrology / instruments
- “Graduation” (or value graduation) is the system of marks on a scale (ruler, gauge, dial) that show numeric values. It includes spacing of divisions, numbering, and the smallest unit (least count). Good graduations let you read measurements accurately; poor graduations introduce reading error or parallax.
2. Visual art / design
- “Value graduation” (also called value gradation) is the smooth transition from light to dark (tonal change) across a surface. Artists use it to model form, create depth, and indicate light direction.
3. Economics / public policy
- Sometimes used to describe a graduated (progressive) scale of values or rates — for example a “graduated tax” or “sliding scale fee” where the rate or charge increases in steps with income or value.
4. Surveys / measurement scales (psychometrics)
- Assigning numeric values to ordered categories (e.g., 1–5 Likert scale) is a kind of value gradation: mapping qualitative responses into a graded numeric scale for analysis.
If you tell me which domain you mean, I’ll give a more specific definition and examples.
