Provided the data are strictly positive, a better measure of relative accuracy can be obtained based on the log of the accuracy ratio: log(F t / A t) This measure is easier to analyze statistically and has valuable symmetry and unbiasedness properties.
A raw score is a score without any sort of adjustment or transformation, such as the simple number of questions answered correctly. A scaled score is the result of some transformation(s) applied to the raw score, such as in relative grading. The purpose of scaled scores is to report scores for all examinees on a consistent scale.
Phred quality scores shown on a DNA sequence trace. A Phred quality score is a measure of the quality of the identification of the nucleobases generated by automated DNA sequencing. [1] [2] It was originally developed for the computer program Phred to help in the automation of DNA sequencing in the Human Genome Project.
When interpreting the clinical scales, the authors recommend that qualified professionals interpret the Severe Clinical Syndrome scales before the Clinical Syndrome scales as the pattern of responding indicated by the Severe Clinical Syndrome scale scores may also affect the scores on the Clinical Syndrome scales (e.g. if an individual scores ...
As a result of this, the ASEBA was able to identify more syndromes than originally identified in the DSM-I. [5] Additionally, this reliance on real-world case records allows the ASEBA to interpret scores in relation to age, gender, and ethnic/racial norms, as symptom/disorder severity and meaning vary across cultures.
A skill score for a given underlying score is an offset and (negatively-) scaled variant of the underlying score such that a skill score value of zero means that the score for the predictions is merely as good as that of a set of baseline or reference or default predictions, while a skill score value of one (100%) represents the best possible ...
The item-total correlation approach is a way of identifying a group of questions whose responses can be combined into a single measure or scale. This is a simple approach that works by ensuring that, when considered across a whole population, responses to the questions in the group tend to vary together and, in particular, that responses to no individual question are poorly related to an ...
Mean opinion score (MOS) is a measure used in the domain of Quality of Experience and telecommunications engineering, representing overall quality of a stimulus or system. It is the arithmetic mean over all individual "values on a predefined scale that a subject assigns to his opinion of the performance of a system quality". [ 1 ]
