Participant studies
Choose Likert, slider, and questionnaire formats
Match response controls to the construct being measured and produce outputs that remain interpretable.
The basic idea
The control should reflect the measurement claim. Likert choices work well for labeled ordered judgments; sliders allow finer-grained responses but can imply precision that participants do not possess. Open text captures explanation but requires a coding plan.
Measure agreement on a five- or seven-point labeled Likert scale, confidence on a bounded 0–100 slider with visible endpoints, and an optional open-text explanation.
How to do it
- 1
Name the construct before choosing the control.
- 2
For Likert items, provide balanced ordered labels and keep direction consistent.
- 3
For sliders, show the current value, meaningful endpoints, range, and step size.
- 4
Preview keyboard, touch, required-state, and exported-value behavior before publishing.
What to watch for
- A 0–100 slider does not automatically provide ratio-scale measurement.
- Avoid double-barreled questions that ask about two things at once.
- Preserve item wording, response labels, order, and coding in the study manifest.
What a useful result looks like
Each response has an understandable participant-facing control and a documented numeric or textual representation suitable for the planned analysis.
