Administering a test to a group of individuals, then computing the average intercorrelation among all items on the test demonstrates the _________ method of estimating reliability.

Classical reliability theory is simply a special case of

The _______ methods of estimating reliability define measurement error strictly in terms of consistency or inconsistency of the content of a test.

Almost all theories of reliability assume that

Errors on different measures are assumed to be

Consistency in test scores is important because

The central assumption of reliability theory is that

True scores and errors are assumed to be

If a student generally does poorly on math exams, but does extremely well on a math test because the student studied only those things on the exam, we could attribute the source of variability in test scores to

Administering a test to a group of individuals, dividing the test into two sections, and correlating the scores on each of the sections demonstrates the ________ method of estimating reliability.
