1. Which statement best captures the purpose of standardization in testing?
A. Making the test easier
B. Guaranteeing validity for every use
C. Ensuring everyone takes the test under the same conditions so scores can be compared with
norms
D. Eliminating all measurement error
Correct Answer: C. Ensuring everyone takes the test under the same conditions so scores
can be compared with norms
Rationale: Uniform procedures make scores comparable.
2. A psychologist uses a test outside their training to make an important custody
recommendation. The main ethical concern is:
A. Test-retest reliability
B. Face validity
C. Item difficulty
D. Practicing outside the boundaries of competence
Correct Answer: D. Practicing outside the boundaries of competence
Rationale: Competence is a core requirement of professional codes.
3. Which group test was used for literate recruits in World War I?
A. Army Beta
B. Army Alpha
C. WAIS
D. MMPI
Correct Answer: B. Army Alpha
Rationale: Army Beta was the nonverbal version.
4. Which describes a criterion-referenced interpretation?
A. 'She correctly performed 18 of 20 required CPR steps'
B. 'She scored at the 85th percentile'
C. 'Her T-score is 60'
D. 'She scored above most of her class'
Correct Answer: A. 'She correctly performed 18 of 20 required CPR steps'
Rationale: The interpretation refers to a defined performance standard.
5. A positively skewed distribution has:
A. A mean less than the median
B. A mean greater than the median
C. Equal mean and median always
D. No tail
Correct Answer: B. A mean greater than the median
Rationale: The long right tail pulls the mean upward.
, 6. A score at the 50th percentile in a normal distribution corresponds to a z-score of:
A. 1
B. -1
C. 0
D. 0.5
Correct Answer: C. 0
Rationale: The median equals the mean in a symmetric normal distribution.
7. A T-score of 60 corresponds to which deviation IQ?
A. 110
B. 120
C. 160
D. 115
Correct Answer: D. 115
Rationale: T = 60 means z = 1; IQ = 100 + 15 = 115.
8. The Spearman rho correlation is appropriate when:
A. Both variables are dichotomous
B. Both variables are ranks (ordinal)
C. One variable is nominal with many categories
D. Data are ratio-level only
Correct Answer: B. Both variables are ranks (ordinal)
Rationale: Rho is the Pearson correlation applied to ranks.
9. Using outdated norms with a modern sample on an intelligence test tends to:
A. Underestimate IQs
B. Overestimate current examinees' IQs
C. Have no effect
D. Change reliability only
Correct Answer: B. Overestimate current examinees' IQs
Rationale: Old norms are easier to surpass because of population gains.
10. Which derived score is NOT on an equal-interval scale?
A. z-score
B. Percentile rank
C. T-score
D. Deviation IQ
Correct Answer: B. Percentile rank
Rationale: Percentile ranks are ordinal.
11. Which source of error does inter-rater reliability address?
A. Differences between scorers
B. Changes over time
C. Item sampling
D. Speededness
Correct Answer: A. Differences between scorers
Rationale: It is crucial for subjectively scored tests such as essays and projectives.
