What are the index scores on the WAIS IV?
There are four index scores representing major components of intelligence:
- Verbal Comprehension Index (VCI)
- Perceptual Reasoning Index (PRI)
- Working Memory Index (WMI)
- Processing Speed Index (PSI)
What is a scaled score WAIS?
Scaled score from 1-7 is described as a weakness or below average with a corresponding percentile rank of 1-16. Scaled score from 8-12 is described as average with a corresponding percentile rank of 25-75. Scaled score of 13-19 is described as a strength or above average with a corresponding percentile rank of 84-99.
What is a composite score on the WAIS?
The Full Scale IQ (FSIQ) composite score is derived from 10 subtest scores and is considered the most representative estimate of global intellectual functioning.
What does the WAIS IV measure?
The WAIS-IV is intended to measure intellectual functioning, incorporating verbal, analogical, sequential, and quantitative reasoning, as well as working memory and psychomotor processing speed.
What does WAIS IV measure?
What does the PSI measure on the WAIS IV?
The PSI measures the speed of mental processing, using visual stimuli and graphomotor skills, and is importantly related to the efficient use of other cognitive abilities.
What is a FSIQ score?
A Composite Score that represents a child’s overall intellectual ability (FSIQ) Primary Index Scores that measure the following areas of cognitive functioning: Verbal Comprehension Index (VCI), Visual Spatial Index (VSI), Fluid Reasoning Index (FRI), Working Memory Index (WMI), and the Processing Speed Index (PSI).
How do you read a composite score?
Your Composite score and each test score (English, mathematics, reading, science) range from 1 (low) to 36 (high). The Composite score is the average of your four test scores, rounded to the nearest whole number. Fractions less than one-half are rounded down; fractions one-half or more are rounded up.
What is a composite score?
What’s a Composite Score? Composite scores represent small sets of data points that are highly related to one another, both conceptually and statistically. Combining and presenting these items as a single score reduces the potential for information overload.
What do you need to know about the WAIS score?
Finally, Processing Speed is how quickly the examinee can process routine information such as reading and reasoning. The first step in analyzing scores is to look at the WAIS Composite Scores for the broadest topics. The Composite Score is the IQ, where the average score is 100.
What is the last column of the WAIS report?
The last column of the WAIS results is simply the Average, High Average, Borderline, etc. description of the test scores. The WAIS report will then break down the different subtests. The first score is the raw score, or how many the examinee got correct.
What are the IQ levels for WAIS IV?
WAIS-IV IQ LEVELS, DESCRIPTIVE CLASSIFICATION AND PERCENTILE RANK IQ Level Descriptive Classification Percentile 130+ Very Superior 98 – 99.9 120 to 129 Superior 91 – 97 110 to 119 High Average 75 – 90 90 to 109 Average 25 – 73 80 to 89 Low Average 9 – 23 70 to 79 Borderline 2 – 8
What does 95% confidence interval in WAIS mean?
If the percentile is 60, for example, he did better than 60% of others who were tested using the WAIS. The 95% Confidence Interval is a statistical way of saying the results sometimes might not be accurate. This statistic says that when taking the test, 95% of the time the results will be in the spectrum given.
