• D. Face validity

Answer: (B)

Verified step by step guidance

1. Step 1: Understand the concept of validity in psychological research, which refers to how well a test or experiment measures what it is intended to measure.
2. Step 2: Recognize that there are different types of validity, such as face validity (how much a test appears to measure what it should), criterion validity (how well one measure predicts an outcome based on another measure), and others.
3. Step 3: Identify that the question asks about determining how much validity is sufficient, which involves comparing the test results to an external criterion or outcome.
4. Step 4: Understand that criterion validity is tested by correlating the test scores with an external criterion that is known to be a valid indicator of the construct being measured.
5. Step 5: Conclude that to determine sufficient validity in the scientific method, researchers typically test for criterion validity, as it provides empirical evidence of how well the test predicts relevant outcomes.
