Tina is trying to maintain her weight. She takes her blood pressure every week. Tina’s blood pressure stays the same, so she believes her weight is being maintained. What can we say about Tina’s blood pressure cuff?
  1. It is reliable
  2. It is valid
  3. It is neither reliable nor valid
  4. It is both reliable and valid
Explanation
Answer: A - Reliability refers to the consistency of a measurement. Validity refers to whether a test measures what it is intended to measure. In this example, Tina’s blood pressure cuff is reliable but not valid. It is reliable because it measures Tina’s blood pressure consistently every week. However, it is not valid because a blood pressure cuff is not an instrument for measuring weight.
