What is the best way to test a measure's reliability over time?
A) test-retest
B) random sampling
C) criterion-related
D) split-half

Question

Quizplus · Accepted Answer

Test-retest is the best way to test a measure's reliability over time as it involves administering the same measure to the same group of individuals at two different points in time and then comparing the results. It measures how consistent the results are over time, indicating the stability of the measure. Random sampling is a method of selecting a representative sample from a larger population and is not specific to testing reliability over time. Criterion-related measures the degree to which one measure is related to another measure or variable of interest. Split-half involves splitting a measure into two parts and comparing the results, which can be a useful method in testing internal consistency but not necessarily for testing reliability over time.
