Question

Quizplus · Accepted Answer

The fact that several clinicians independently arrived at the same diagnosis using the new diagnostic system suggests that it is reliable. Reliability refers to the consistency and reproducibility of results, and this is a key characteristic of a good diagnostic system. The other answer choices are not necessarily supported by the information given. Standardization (choice A) refers to the use of consistent procedures and criteria across different settings, and this has not been demonstrated here. Norming (choice C) refers to the establishment of reference values or norms for a particular diagnostic tool, which may or may not be relevant in this case. Validity (choice D) refers to the accuracy and meaningfulness of a diagnostic system in measuring what it is supposed to measure, and this information is not provided in the scenario. While a reliable diagnostic system is necessary for a valid one, the reverse is not always true.
