B
Feedback:
Ratio measurement is the highest level of measurement. Ratio scales, unlike interval scales, have a meaningful zero and thus provide information about the absolute magnitude of the attribute. A person's twenty-four-hour oral cc intake has a meaningful zero; that is, the absolute amount of oral intake may be measured. Likert scale responses and ability to perform activities of daily living are examples of ordinal measurement, which ranks people based on relative standing on an attribute but cannot indicate the distance between them. Eye color is an example of nominal measurement, which involves using numbers simply to categorize attributes.
