When to use it
- The answer is a magnitude on a continuous range — an amount, a percentage.
- A tactile, playful control fits the audience and boosts engagement.
- You want fine gradations that discrete radio buttons would clutter.
- The range has intuitive endpoints respondents grasp immediately.
When to reach for something else
- Precision matters — a number entry field is less error-prone than a drag.
- Accessibility or older devices are a concern — a labeled scale is safer.
- A starting handle position could anchor the answer and bias results.
Sample question
“Roughly what percentage of your monthly budget goes toward groceries? (Drag the slider from 0% to 100%.)”
Best practices
- Show the current value as the handle moves so the choice is unambiguous.
- Set a sensible step size — whole numbers unless fine detail is needed.
- Start unset (no pre-filled handle) to avoid anchoring the response.
- Label the endpoints and units clearly so the range reads correctly.
- Provide a keyboard and touch fallback so the slider isn’t drag-only.
Data & reporting
Each response stores the numeric value. Exports write that number into one column. Reports compute the mean, minimum, maximum, and distribution across the range — the same numeric summary as a rating scale, just captured on a continuous control.
Accessibility
The slider is a labeled range control adjustable with the arrow keys (not drag alone), announces its current value, minimum, and maximum to assistive technology, and keeps a visible value readout so the position isn’t the only cue.
Compared to SurveyMonkey
Both provide slider inputs; Surveti’s slider ships with a keyboard-operable range control and a live value readout, and reports the mean and distribution alongside your other numeric questions.
Frequently asked questions
Is a slider better than a rating scale?
Not automatically. Sliders feel engaging and suit continuous magnitudes, but they can be fiddly on touch devices and a starting handle position can bias the answer. For simple, precise ratings, a labeled scale is often the safer choice.
Should the slider start at a default value?
Prefer starting it unset. A pre-positioned handle anchors respondents toward that value and inflates it as a “default” answer. An unset start makes the respondent commit to a real position.
How does slider data report?
As a numeric summary — mean, minimum, maximum, and the distribution across the range — identical to how a rating scale reports, so the two are directly comparable.
