Opinion scale and metrics

Choose the right scale for clarity, recommendation, satisfaction or usability.

What it does

Turn a subjective assessment into a numeric answer with clear endpoints.

When to use it

To compare ratings using the same question and range; use ready-made batteries when you need SUS or UMUX-Lite.

Before you begin
  • Define the concept: clarity, satisfaction, recommendation or ease.
  • SUS, UMUX-Lite and SEQ come from New study templates; they are not additional presets in the scale editor.

Ask about clarity

Add Opinion scale and write a specific rating question.

  • How clear was the receipt?

An example to try

How clear was the receipt?

  • 1 Not clear at all
  • 5 Very clear

What you see in results

  • Read the distribution, base and metric appropriate to the question.
  • SUS and UMUX-Lite require complete batteries; the system does not invent missing items.

Avoid these mix-ups

  • Do not call every 0–10 scale NPS: the question must ask about recommendation.
  • Do not remove or duplicate items within a standardized battery and expect the same scoring.
