Making Inferences about the Domain

Usually when we administer a test, it is the domain, not the test per se, which is of interest. The particular test questions are of interest only in so far as they permit us to make inferences about the whole domain in relation to the test-taker, the institution, or the program.

Inferences About Individuals

Inferences about Groups

Inferences About a Larger Group

Sometimes, test results are used to make inferences about a much larger group. For example, a sample of classrooms may be tested to represent state performance.

Inferences About a Different Domain

Test results can lead to inferences that refer to a different domain than the one tested.

For example, SAT items tap Verbal and Math ability, but the test is used to predict college performance.
