A Polarity Scale question, or semantic differential, is used to obtain responses on a sliding scale between two extremes. When you add a polarity scale to a questionnaire, you can use a single question to ask about one or more aspects, qualities, or perceptions about that item at the same time. Each scale becomes a Sub-question since each one will have a unique response.

On the Results page, responses are presented in Intensity mode, or the degree to which respondents moved away from the center toward one side of the scale or another.
- Drag the second toggle from Pairs to Delta to view the calculated "winner" of each pair.
- Click the word Median to toggle the view between Median and Mean responses.
- Toggle from Intensity to Popularity to view how many people left their slider on one side or another. If neutral answers were allowed, some grey gaps may appear in the center of the chart, indicating the percentage of undecided respondents.
- Use the Popularity slider to adjust the rules of what you count as a neutral or undecided answer, regardless of whether you allowed neutral answers or not in the survey.
