A 'confidence interval' reported around an FSIQ reflects what?
Answer: The range likely to contain the true score given measurement error
Confidence intervals account for the standard error of measurement around an obtained score.
Why are Wechsler norms periodically restandardized on new samples?
Answer: To account for the Flynn effect and population change
Restandardization corrects for gradual score gains over time known as the Flynn effect.
Using outdated Wechsler norms tends to do what to an examinee's apparent IQ?
Answer: Inflate it
Older norms become easier over time, so scores tend to be inflated relative to current norms.
The standard error of measurement (SEM) on the Wechsler is related to which test property?
Answer: Reliability
SEM is derived from a test's reliability; higher reliability yields a smaller SEM.
Wechsler normative samples are designed to be representative of what?
Answer: The general population stratified by demographics
Standardization samples are stratified by age, sex, region, education, and ethnicity to match the population.
When two index scores differ, a 'base rate' tells the examiner what?
Answer: How common that size of difference is in the normative sample
Base rates indicate how frequently a given discrepancy occurs in the standardization sample.
A scaled score of 1 to 3 on a Wechsler subtest indicates performance that is what?
Answer: Well below average
Scaled scores of 1–3 fall more than two SDs below the subtest mean of 10, indicating a marked weakness.
