Likert scale data can, in principle, be used as a basis for obtaining interval level estimates on a continuum by applying the polytomous Rasch model, when data can be obtained that fit this model. In addition, the polytomous Rasch model permits testing of the hypothesis that the statements reflect increasing levels of an attitude or trait, as ...

A rating scale is a set of categories designed to obtain information about a quantitative or a qualitative attribute. In the social sciences, particularly psychology, common examples are the Likert response scale and 0-10 rating scales, where a person selects the number that reflecting the perceived quality of a product.
For example, applications of measurement models in educational contexts often indicate that total scores have a fairly linear relationship with measurements across the range of an assessment. Thus, some argue that so long as the unknown interval difference between ordinal scale ranks is not too variable, interval scale statistics such as means ...
Psychological statistics is application of formulas, theorems, numbers and laws to psychology. Statistical methods for psychology include development and application statistical theory and methods for modeling psychological data. These methods include psychometrics, factor analysis, experimental designs, and Bayesian statistics. The article ...
Developed by Judith Hibbard and colleagues at the University of Oregon, the resulting 13-item measure is a uni-dimensional, interval level, Guttman-like scale. [ 1 ] [ 2 ] The PAM has strong psychometric properties, and has been translated into 22 different languages. [ 3 ]
This score sheet is usually in the form of a bell curve where a respondent can place most Q sorts at the middle and the fewest Q sorts at the far ends of the score sheets. The sample of statements for a Q sort is drawn from and claimed by the researcher to be representative of a "concourse"—the sum of all things people say or think about the ...
The two values on the VAS-scales are added up to give a total score ranging from 0 to 100. [8] Higher scores indicate higher levels of fear, and the cut-off point for fear of birth is 60. [ 9 ] Later on, FOBS, was then developed and tested based on Rouhe’s research in pregnant women in both Sweden and Australia.
