When researchers want to test robustness,or how well an operational protocol is working,they might use which of the following techniques?
A)the test-retest method
B)vetting
C)face validity
D)a normal distribution

Question

Quizplus · Accepted Answer

The test-retest method involves measuring the same variable at two different times and comparing the results. This allows researchers to determine whether the operational protocol is stable over time and is therefore a useful technique for testing robustness. Vetting is a process through which experts review and provide feedback on a protocol, but it does not directly measure robustness. Face validity refers to whether a measure appears to be measuring what it is intended to measure, but this is not necessarily the same as robustness. A normal distribution is a statistical concept and is not directly related to measuring the robustness of an operational protocol.
