CVE Psychometric Testing & Interpretation 2

Question 1

A vocational evaluator uses a norm-referenced test and finds a client scores at the 25th percentile. What does this mean?

Accepted Answer

The client scored higher than 25% of the normative sample

Answer

A percentile rank of 25 means the client scored equal to or higher than 25% of individuals in the normative comparison group.

Question 2

Which type of reliability assesses consistency of a test across two different forms of the same instrument?

Accepted Answer

Alternate forms reliability

Answer

Alternate forms (parallel forms) reliability measures how consistently two different versions of the same test produce equivalent scores.

Question 3

In psychometric testing, what does a standard error of measurement (SEM) represent?

Accepted Answer

The estimated variability in a person's scores due to measurement error

Answer

SEM estimates the amount of error in an individual's observed score, defining a confidence interval around the true score.

Question 4

A test has high specificity but low sensitivity. In vocational assessment, this means the test is better at:

Accepted Answer

Correctly ruling out individuals without the trait

Answer

High specificity means the test correctly identifies true negatives—those who do not have the condition or trait being assessed.

Question 5

Which scale of measurement allows calculation of meaningful ratios, such as 'twice as fast'?

Accepted Answer

Ratio

Answer

Ratio scales have a true zero point, making ratios between scores mathematically meaningful.
