Perceptions of tied ranks and equal intervals on a modified visual analog scale
Timbrook, J. P., & Moroney, W. (2016). Ranking: Perceptions of tied ranks and equal intervals on a modified visual analog scale. Survey Practice, (3). https://doi.org/10.29115/sp-2016-0019
This study examined a novel paper-based ranking system (called the BINS format) that was designed to address two limitations of traditional ranking formats. This new system allows respondents to: 1) assign ties to ranked alternatives and 2) indicate distance between ranked alternatives. Participants reported high satisfaction with the ability to express ties using the BINS format, and preferred to use a ranking format that allowed for ties over a format that did not. Two versions of the BINS format (a numbered continuum and an unnumbered continuum) were compared to examine participants’ perception of the distance between ranked alternatives. When a numbered continuum was used, participants saw the relationship between ranked alternatives as both multiplicative and divisible; conversely, participants using the unnumbered continuum did not see either relationship. This lends support to the notion that participants perceived the numbered BINS format as having equal psychological intervals.
