Wechsler Test Wechsler Scoring and Normative Data 5

Question 1

A 'confidence interval' reported around an FSIQ reflects what?

Accepted Answer

The range likely to contain the true score given measurement error

Answer

Confidence intervals account for the standard error of measurement around an obtained score.

Question 2

Why are Wechsler norms periodically restandardized on new samples?

Accepted Answer

To account for the Flynn effect and population change

Answer

Restandardization corrects for gradual score gains over time known as the Flynn effect.

Question 3

Using outdated Wechsler norms tends to do what to an examinee's apparent IQ?

Accepted Answer

Inflate it

Answer

Older norms become easier over time, so scores tend to be inflated relative to current norms.

Question 4

The standard error of measurement (SEM) on the Wechsler is related to which test property?

Accepted Answer

Reliability

Answer

SEM is derived from a test's reliability; higher reliability yields a smaller SEM.

Question 5

Wechsler normative samples are designed to be representative of what?

Accepted Answer

The general population stratified by demographics

Answer

Standardization samples are stratified by age, sex, region, education, and ethnicity to match the population.
