Which scale is a horizontal line with anchor points at each end and descriptors spread along the line?

Which scale is a horizontal line with anchor points at each end and descriptors spread along the line?

• A. Graphic rating
• B. Visual analog scale
• C. Visual rating scale
• D. Number scale

Answer: (A)

This is about how the scale is laid out and anchored. A graphic rating scale uses a horizontal line with anchor points at the ends and multiple descriptors spread along the line, giving several qualitative anchors between the extremes. Respondents mark the point that best represents their perception, which allows for nuanced judgments across a continuum. By contrast, a visual analog scale typically has a line with endpoints but no descriptors along it, and a number scale relies on numeric values rather than descriptive terms along the line. So the description most accurately matches a graphic rating scale.
