B) parallel forms
C) split-half
D) test-retest

Question

Quizplus · Accepted Answer

Parallel forms reliability involves creating two equivalent forms of a test that measure the same construct, skill, or knowledge base, and then administering both forms to the same group of individuals. The consistency of the results across the two forms accounts for error variance due to different samples of test items (since each form has different items) and can also account for different conditions of administration if the two forms are administered under varied conditions. This type of reliability is designed to assess the extent to which different forms of the test are interchangeable, making it the correct answer for considering both types of error variance mentioned.
