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 .
The source reliability is rated between A (history of complete reliability) to E (history of invalid information), with F for source without sufficient history to establish reliability level. The information content is rated between 1 (confirmed) to 5 (improbable), with 6 for information whose reliability can not be evaluated.
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 ...
Lewis M. Terman, a psychologist at Stanford University, was one of the first to create a version of the test for people in the United States, naming the first localized version the Stanford revision of the Binet-Simon Intelligence Scale (1916) and the second version the Stanford–Binet Intelligence Scale (1937).

Pattern Reasoning (ages 5 and 6). Story Completion (ages 5 and 6). Sequential/Gsm. Word Order: The assessor reads the names of common objects, the child the touches a series of silhouettes of these objects in the same order they were read out in. Number Recall: The assessor reads a string of numbers and the child repeats the string in the same ...
Level of measurement or scale of measure is a classification that describes the nature of information within the values assigned to variables. [1] Psychologist Stanley Smith Stevens developed the best-known classification with four levels, or scales, of measurement: nominal , ordinal , interval , and ratio .
Terman chose the category names for score levels on the Stanford–Binet test. When he first chose classification for score levels, he relied partly on the usage of earlier authors who wrote, before the existence of IQ tests, on topics such as individuals unable to care for themselves in independent adult life.
