Question

An individual's WAIS-IV results include the following data. Explain what each of following mean in a way that would b understandable to someone not familiar with the test or with psychometrics.

A. Full scale
B. Sum of scaled score = 96
C. FSIQ=97
D. 42 percentile rank
E. 95% confidence interval= 93-101

Answer 1

The WAIS-IV is an intelligence test that measures an individual's cognitive abilities. The Full scale score represents the overall measure of intelligence, while the sum of scaled scores is the total score across all subtests. FSIQ indicates the individual's overall intellectual functioning, percentile rank compares their scores to others, and the confidence interval provides a range of likely scores.

Step-by-step explanation:

The WAIS-IV is an intelligence test that measures an individual's cognitive abilities. Here's what each of the given data mean:

A. Full scale:

The full scale score is the overall measure of an individual's intelligence. It combines the scores from all the subtests of the WAIS-IV.

B. Sum of scaled score = 96:

The sum of scaled scores represents the total score achieved across all subtests, which in this case is 96.

C. FSIQ=97:

The FSIQ (Full Scale Intelligence Quotient) is a standardized score that represents an individual's overall intellectual functioning. An FSIQ of 97 indicates average intelligence.

D. 42 percentile rank:

The percentile rank tells you how you compare to others who took the test. A percentile rank of 42 means that you scored higher than 42% of the population.

E. 95% confidence interval = 93-101:

The confidence interval provides a range of scores within which the true score is likely to fall. In this case, there is 95% confidence that the true score falls between 93 and 101.

Answer 2

The WAIS-IV assessment provided includes Full Scale IQ, a measure of general cognitive ability; Sum of Scaled Score, a cumulative measure of subtests; an FSIQ of 97, indicating average intelligence; a 42nd Percentile Rank, suggesting performance better than 42% of peers; and a 95% Confidence Interval, a range where the true score likely falls.

Step-by-step explanation:

An individual's WAIS-IV results include the following data:

• Full Scale: This refers to the Full Scale IQ score, which is a general measure of cognitive ability derived from all the subtest scores.
• Sum of Scaled Score = 96: Scaled scores are totals of individual subtest scores that have been statistically adjusted. A Sum of Scaled Score of 96 suggests that this individual's sum of scores across different cognitive areas falls near the average.
• FSIQ = 97: FSIQ stands for Full Scale Intelligence Quotient. A score of 97 is close to the overall population mean of 100 and considered average intelligence.
• 42 Percentile Rank: This means that the individual scored better than 42% of their peers. Percentiles rank the scores in relation to a normative sample.
• 95% Confidence Interval = 93-101: This range indicates that there is a 95% chance that the individual's true IQ score falls within the given range, considering possible testing variability.
