Final answer:
It is false to assert a test can be completely valid without content validity since content validity ensures the test measures the entire range of the subject matter.
Step-by-step explanation:
It is false that a test can have excellent empirically-based support for its validity without having any content validity. Content validity refers to how well a test measures the entire range of material it is supposed to cover. If a test lacks content validity, it cannot be said to have a comprehensive empirical basis because it would fail to assess all relevant aspects of the subject matter. Thus, these types of validity are interconnected, and a test would need both to be considered truly valid in a comprehensive sense.
