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 .
The test takes 45–90 minutes to administer depending on the age of the participant. The mean score for the WIAT-II is 100 with a standard deviation of 15, and the scores on the test may range from 40 to 160. 68% of participants in the UK standardisation sample obtained scores of 85-115 and 95% obtained scores of 70-130.
A Perceptual Reasoning Index (PRI) can be derived from the raw scores on the Matrix Reasoning and Block Design subtests. A Full Scale IQ-2 (FSIQ-2) can be derived from the raw scores on the Matrix Reasoning and Vocabulary subtests, while a Full Scale IQ-4 (FSIQ-4) can be derived from the raw scores on all 4 subtests. WASI-II Subtests grouped by ...
The WISC can be used to show discrepancies between a child's intelligence and his/her performance at school (and it is this discrepancy that school psychologists look for when using this test). [citation needed] [4] In a clinical setting, learning disabilities can be diagnosed through a comparison of intelligence scores and scores on an ...
The results of the two tests correlate approximately inversely: a text with a comparatively high score on the Reading Ease test should have a lower score on the Grade-Level test. Rudolf Flesch devised the Reading Ease evaluation; somewhat later, he and J. Peter Kincaid developed the Grade Level evaluation for the United States Navy.
Average math scores on the National Assessment of Educational Progress tests fell 7 points to 234 on a 0-500 scale. For students performing in the bottom 10%, the drop was 12 points, compared with ...
The Differential Ability Scales (DAS) is a nationally normed (in the US), and individually administered battery of cognitive and achievement tests. Into its second edition (DAS-II), the test can be administered to children ages 2 years 6 months to 17 years 11 months across a range of developmental levels. [1]
In technical terms, the pattern of scores by individual students to individual items is used to infer so-called scale locations of students, the "measurements". This process is one form of scaling. Essentially, higher total scores give higher scale locations, consistent with the traditional and everyday use of total scores. [1]
