Question

A job applicant applied twice to the same organization. The first time, the applicant

did very poorly on the selection test, but then scored very high 4 weeks later. What
can be concluded about the selection test?
a) It has low validity.
b) It has low reliability.
c) It has range restriction.
d) It has test-retest bias.

Answer 1

The significant difference in scores from the job applicant suggests that the selection test likely has low test-retest reliability, meaning it is not consistent over time.

Step-by-step explanation:

If a job applicant scored very poorly on a selection test and then scored very high 4 weeks later, it suggests there may be issues with the test-retest reliability of the selection test. Test-retest reliability is a form of reliability that assesses an instrument's consistency over time. If the selection test were reliable, the applicant's scores should be relatively stable and consistent across the two test sessions, assuming the applicant's abilities did not significantly change in such a short period. Therefore, the correct conclusion in this scenario is that the selection test has low reliability.
