Which validity concept refers to whether a Wechsler subtest actually measures the underlying construct, such as working memory, it claims to assess?
Answer: Construct validity
Construct validity addresses whether a test measures the theoretical trait it is intended to measure.
Factor analysis of the WISC-V supports how many primary index scores?
Answer: Five
The WISC-V is organized around five primary index scores: Verbal Comprehension, Visual Spatial, Fluid Reasoning, Working Memory, and Processing Speed.
Which index score was newly separated out in the WISC-V compared to the WISC-IV's Perceptual Reasoning Index?
Answer: Fluid Reasoning Index
The WISC-V split perceptual reasoning into separate Visual Spatial and Fluid Reasoning indexes.
A test that produces consistent scores but does not measure what it intends to measure is best described as:
Answer: Reliable but not valid
Consistency without accuracy means the test is reliable but not valid.
The process of administering a Wechsler test to a large representative sample to establish norms is called:
Answer: Standardization
Standardization establishes uniform administration procedures and normative reference data using a representative sample.
Why are raw scores on Wechsler subtests converted to scaled scores before interpretation?
Answer: To adjust for the examinee's age group
Raw scores are converted to age-based scaled scores so performance can be compared to same-age peers.
Which coefficient is commonly reported as a measure of a Wechsler subtest's internal consistency reliability?
Answer: Cronbach's alpha
Cronbach's alpha is widely used to estimate internal consistency reliability.
