Abstract
- Unnumbered graphic rating scales theoretically can lead to greater score variance and thus greater score reliability. The use of Web-based graphic sliders overcomes the practical problems of administering graphic scales on paper measures: the excessive costs of scoring and excessive scoring errors arising from the tediousness of scoring done by hand. The study investigated whether graphic scales realize theoretically expected improved score reliability and how coarseness in slider scoring affects reliability. A large sample size (n = 4,407) and diverse respondent groups were employed so that more confidence could be invested in results. [ABSTRACT FROM AUTHOR]
