PTO
5. Why do most tests contain more than one norm?
a. Because tests can be evaluated in different ways
b. Because there is no right answer to any test
c. Because of the margin of error

d. Spearman’s Rho
9. Which form of validity indicates whether a test can be used to predict a real-world external
criterion?
a. face-validity
b. concurrent validity
c. criterion-related validity
d. construct validity
10. When using a test to gain a broad overall impression of an individual, which form of
validity would you be seeking?
a. face-validity
b. concurrent validity
c. criterion-related validity
d. construct validity

university, which form of validity would you emphasise?
a. concurrent criterion related validity
b. construct validity obtained concurrently
c. Predictive criterion related validity
d. face-validity
12. If you are concerned about the acceptability of a well-researched vocational interest test
for use with potentially uncooperative trainees, which form of validity would you look for?
a. criterion related validity obtained concurrently
b. pseudo-validity
c. criterion-related validity obtained predictively
d. face-validity
13. If a test correlates significantly with job performance it suggests that:
a. the correlation between test and job performance is greater than zero
b. the test correlates highly with job performance
c. the relationship between test and job performance is very likely to have occurred by chance
d. the relationship between test and job performance is unlikely to be a random or chance
occurrence
14. The best way to demonstrate construct validity is to:
a. Obtain a large representative norm sample for the test
b. Correlate the test with independently derived measures of job performance
c. Correlate the test with independently derived measures of the same psychological construct
d. check questions to ensure that they are suitable for the intended purpose
15. What does it mean if the criterion-related validity coefficient for a test is negative?
a. the test is invalid
b. scores on the test are unrelated to the criterion
c. The test is valid
d. high scores on the test are related to low criterion performance

PART TWO
1. What are the two principal test categories and provide named egs of each?
2. What is reliability and how does it relate to the standard error of measurement?
3. What effect does increasing the reliability of a test have on its SEM?
4. Explain why an unreliable test cannot be valid.
5. Name three major sources of error (unreliability) in psychometric assessment.
6. In what way would knowledge of test scores when of rating job performance
influence the criterion validity coefficient found in a criterion validity study
(remember this is called criterion contamination)
7. In what way would poor reliability of the criterion (e.g. job performance) measure influence the criterion related validity coefficient found in a validity study?
8. Describe what is meant by restriction of range in test scores and what effect would this have on the results of a criterion validity study?
9. Explain the difference between criterion and norm referenced use of tests.
10. Describe what is meant by Correlation and then make a rough sketch of a scatter
plot to illustrate:
(a) A high positive correlation between two test measures
(b) A moderate correlation between a test results
(c) A low negative correlation between a personality measure and job performance
11. Explain your obligation towards respondents re test scores under the Data
Protection Act?
12. What would it mean if we found female applicants generally scored less well on
a selection test, but there were no differences in measures of job performance?
13. What would you do (if anything) if you found the scores of a minority group of
candidates to be significantly lower than that of the majority?
14. What do best practice standards say about making a test report available for a
purpose for which it was not originally intended and for which consent was not
gained?
