Final answer:
In testing, reliability is related to the consistency of results, like precision, whereas validity corresponds to the accuracy of those results, ensuring the test measures what it's supposed to.
Step-by-step explanation:
In testing, reliability refers to the consistency of results, meaning if you perform the same test under the same conditions, reliability would ensure that you get similar outcomes each time. This concept is akin to the precision of measurements in other fields. On the other hand, validity is likened to the accuracy of results. It assesses whether a test measures what it is intended to measure. Therefore, a test that yields accurate results must be valid, capturing the true attributes or performance it is supposed to measure. Given this understanding, the appropriate pairing is d. reliability; validity.
