Interval-level measurement with visual analogue scales in Internet-based research: VAS Generator.
The present article describes VAS Generator (www.vasgenerator.net), a free Web service for creating a wide range of visual analogue scales that can be used as measurement devices in Web surveys and Web experimentation, as well as for local computerized assessment. A step-by-step example for creating and implementing a visual analogue scale with visual feedback is given. VAS Generator and the sc...
متن کاملUse of visual analogue scales.
G. R. V. HUGHES plates. Sixteen wells 3 mm in diameter and 1-5 mm apart are cut in a row, and a trough 3 mm wide is cut parallel to the wells 3 mm from their cathodal side. Heat inactivated sera (8 .lI) are added to the wells, and a tissue extract containing soluble antigens (150 ,ul) is placed in the trough. We use human spleen extract4 or rabbit thymus extract at a final protein concentration...
متن کاملWhy Semantic Differentials in Web-Based Research Should be Made From Visual Analogue Scales and Not From 5-Point Scales
In a Web experiment, participants were randomly assigned to 2 semantic differentials either made from discrete 5-point ordinal rating scales or from continuous visual analogue scales (VASs) with 250 gradations. Respondents adjusted their ratings with VASs more often to maximize the precision of answers, which had a beneficial effect on data quality. No side effects like differences in means, hi...
متن کاملEnhancements to the Visual Analogue Scale, VAS, for listening tests
Three methods for perceptual rating of audio stimuli were compared. The Visual Analogue Scale, VAS, was implemented as two computer programs and compared to the VAS on paper. The first program is a straight-forward implementation, the second program introduces the Visual Sort and Rate method, VSR. VSR allows the subject to compare stimuli of similar rating to each other, thus making the orderin...
متن کاملVertical or horizontal visual analogue scales.
Vertical and horizontal visual analogue scales have been compared in the measurement of pain. There was a good correlation between the 2 scales, but the scores from horizontal scales tended to be slightly lower than those from vertical scales.
