The FSIQ is determined by the sum of the scaled scores from the 10 subtests of the WISC (each subtest’s scaled score can range from 1-19, higher if extended norms are used; the scaled scores are NOT the same as the composite scores that have a mean of 100).
How is full scale IQ calculated Wisc V?
The Full-Scale IQ score is derived from seven subtests and summarises ability across the five areas of cognitive ability: Verbal Comprehension, Visual-Spatial, Fluid Reasoning, Working Memory and Processing Speed indexes. The WISC–V Full-Scale score is one way to view a child’s general intellectual functioning.
How do you calculate full scale IQ on WAIS IV?
To obtain each index score, the sum of scaled scores is computed for the core subtests that comprise each index and then converted to a standard score. To obtain the Full Scale IQ Index score, the sum of scaled scores is computed for the 10 core subtests and then converted to a standard score (M = 100; SD =15).

How is FSIQ Wais calculated?
The FSIQ is calculated as the sum of all scaled scores for three items on the Verbal Index and Perceptual Reasoning Index each and two items from the Working Memory Index and Processing Speed Index, usually the most ‘g’ loaded. Calculated as 25+ (sum of scaled scores) * .
What is perceptual reasoning on an IQ test?
Perceptual Reasoning Index: A measure of an individual’s ability to understand visual information and to solve novel abstract visual problems. This is what we are referring to when we speak about an individual’s measured IQ.
What does the WAIS-IV measure?
Wechsler Adult Intelligence Scale-IV DESCRIPTION OF WAIS-IV INDEXES Verbal Comprehension Index This index reflects an individual’s ability to understand, use and think with spoken language. It also demonstrates the breadth and depth of knowledge acquired from one’s environment. It measures the retrieval from long-term memory of such information.
What is the full scale IQ?
The Full Scale IQ is an averaging of these five scales, so it’s only meaningful if the scales are consistent. If a child is superior in verbal reasoning, but below average in visual spatial skills, the full scale number looks average.
What is the Wechsler Adult Intelligence Scale (WAIS-IV)?
Psychologists are often asked to administer the WAIS-IV (Wechsler Adult Intelligence Scale – Fourth Edition). The WAIS-IV is the “gold standard” in cognitive assessment and claims to measure intellectual performance.
