CVE Psychometric Testing & Interpretation 3 — Questions and Answers
Question 1: Which statistical concept describes the tendency of extreme scores on a first testing to move closer to the mean on a second testing?
- Standard deviation
- Regression to the mean (Correct answer)
- Skewness
- Kurtosis
Correct answer: Regression to the mean
Regression to the mean occurs because extreme scores partially reflect measurement error, which is random and unlikely to repeat in the same direction.
Question 2: The McCarron-Dial System (MDS) is primarily used in vocational evaluation to assess:
- Career interests and job satisfaction
- Neuropsychological and behavioral functioning for work potential (Correct answer)
- Physical stamina and endurance
- Reading and mathematical computation
Correct answer: Neuropsychological and behavioral functioning for work potential
The MDS evaluates neuropsychological, emotional, integration-coping, motor, and verbal-cognitive factors to predict vocational functioning.
Question 3: Content validity is best established through:
- Correlating test scores with a criterion measure
- Factor analysis of test items
- Expert review to confirm items represent the domain being measured (Correct answer)
- Test-retest comparisons over time
Correct answer: Expert review to confirm items represent the domain being measured
Content validity is demonstrated when subject-matter experts confirm that test items adequately sample the full range of the construct being measured.
Question 4: In the context of the APTICOM system, what does the instrument measure?
- Physical work tolerances and endurance
- Aptitudes and interests aligned with the Dictionary of Occupational Titles worker trait requirements (Correct answer)
- Personality characteristics for team environments
- Post-secondary academic potential
Correct answer: Aptitudes and interests aligned with the Dictionary of Occupational Titles worker trait requirements
APTICOM assesses multiple aptitudes and vocational interests matched to the DOT's worker trait group requirements for occupational exploration.
Question 5: A normal distribution is described as platykurtic. This means the distribution is:
- More peaked than a normal curve with heavy tails
- Flatter than a normal curve with lighter tails (Correct answer)
- Skewed to the right
- Bimodal with two distinct peaks
Correct answer: Flatter than a normal curve with lighter tails
A platykurtic distribution is flatter and broader than the normal bell curve, with fewer scores near the mean and lighter tails.
Question 6: Which validity type is demonstrated when a new vocational test correlates strongly with an established, accepted measure of the same construct?
- Predictive validity
- Convergent validity (Correct answer)
- Discriminant validity
- Face validity
Correct answer: Convergent validity
Convergent validity is evidenced when a new measure correlates highly with existing measures that assess the same or theoretically related constructs.
Question 7: When a vocational evaluator reports a confidence interval of 90–110 for a client's IQ score, this means:
- The client's true score is exactly 100
- There is a specified probability (e.g., 95%) that the true score falls within this range (Correct answer)
- The client passed 90–110 items on the test
- The score is in the average range only if it equals 100
Correct answer: There is a specified probability (e.g., 95%) that the true score falls within this range
A confidence interval represents the range within which the client's true score is likely to fall, accounting for measurement error at a given confidence level.
