When one "attempts to estimate the reliability of all the possible split half combinations" of a test, one is assessing what kind of reliability?

A) Test-retest
B) Alternate forms
C) Parallel forms
D) Coefficient Alpha
E) None of these

This is an assessment of the reliability of all possible split-half combinations, which is a measure of the internal consistency of the test. Coefficient alpha is a common method for assessing internal consistency reliability. Test-retest reliability is the extent to which the same test produces consistent results over time, while alternate and parallel forms reliability both involve administering different but equivalent versions of a test to the same group of people to assess consistency across forms.
