C36 · Reference edition 2026.11
Comparison order — Definition and boundaries
Order can affect an observer’s reference point. A comparison record should preserve the actual sequence and the intended comparison question.
Scope and purpose
Start by separating the named concept from adjacent concepts. Use the observation below to identify the question the record is intended to answer. Read the caution before applying the example. A definition is useful only when another reader can tell what falls outside it.
Working notes
This atlas connects descriptive vocabulary, observation context and reference-sheet design. All example records are synthetic and exist to explain a method of documentation; they do not represent tested batches, product ratings or scientific results. The diagrams are original editorial graphics. Descriptions of perceived character are kept separate from ingredient, origin, health and certification claims. Read definitions and scale anchors before comparing records.
Practical example
Display the sequence beside the notes rather than rearranging samples after observation.

| C36 | Comparison order |
| Scope and purpose | Order can affect an observer’s reference point. A comparison record should preserve the actual sequence and the intended comparison question. |
| Limits and interpretation | A single sequence cannot establish that order effects were controlled. |
Review checklist
Write a one-sentence scope statement; identify a neighbouring concept; record what the example does not establish.
