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 ...
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 ...

Scores for individuals in each age group are norm-referenced. The ASEBA has been translated in one hundred languages, and has a variety of multicultural applications. [2] Each report form in the ASEBA System has 113 items, but there is not a one-to-one correspondence between each individual item across the different report forms.
While mean scores from Likert-type scales can be compared across individuals, scores from an ipsative measure cannot. To explain, if an individual was equally extraverted and conscientious and was assessed on a Likert-type scale, each trait would be evaluated singularly, i.e. respondents would see the item "I enjoy parties" and agree or disagree with it to whatever degree reflected their ...
The total score refers to the sum of both the Yield and Shift scores. [1] In a sample of 195 people, the Yield 1 mean score was 4.9, with a standard deviation of 3.0. The Yield 2 mean score was 6.9, with a standard deviation of 3.4. The average Shift score was 3.6, with a standard deviation of 2.7.
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 ...
