An investigator computed the split-half reliability coefficient of a test and found it to be .85.Later an equivalent form of the test was prepared and the reliability computed by administering the two forms to a group.One might expect that the reliability coefficient obtained by the latter procedure would be
A) lower than .85.
B) higher than .85.
C) also .85.

Question

The reliability coefficient obtained by administering two forms of a test (equivalent-forms reliability) is typically lower than the split-half reliability coefficient because it accounts for more sources of error variance, such as differences between the forms and conditions under which each form is administered.
