Final answer:
Validity refers to how well a measure accurately measures what it's supposed to measure. While any valid measure is reliable, the reverse is not necessarily true. Researchers strive to use instruments that are both highly reliable and valid.
Step-by-step explanation:
The question asks if a measure is considered valid if it produces data that agree with a known standard. The correct answer is (B) False. Validity refers to how well a given instrument or tool accurately measures what it's supposed to measure. To determine the validity of a measure, researchers consider factors such as ecological validity, construct validity, and face validity. While any valid measure is reliable, the reverse is not necessarily true. Researchers strive to use instruments that are both highly reliable and valid.
