The precision of a test refers to test reliability as measured by what method?
A)Alternate-form
B)Internal consistency
C)Split-half
D)Test-retest

Question

Quizplus · Accepted Answer

The precision or reliability of a test is usually measured using internal consistency methods such as Cronbach's alpha or split-half reliability. These methods assess the consistency of different items or subscales within the same test. While alternate-form and test-retest reliability are also measures of test consistency, they relate more to the stability of the test over time or the equivalence of different test forms. Therefore, B) Internal consistency is the best choice for the precision of a test.
