D) the test is not vulnerable to random error.

Question

Quizplus · Accepted Answer

A reliable test should provide consistent results over time when measuring the same construct (in this case, intelligence). Therefore, if Marko takes the IQ test twice and the results are not similar, it suggests that the test might not be reliable. Therefore, Choice A is the best answer as it indicates that Marko should score similarly both times he takes the test. It's worth noting that reliability does not guarantee accuracy, sensitivity, or being immune to random error.
