Dr. Lopez is assessing how well new drivers recognize road signs from far away. He does this by testing their eyesight, as well as how they perform on a driving simulation task. Their eyesight scores are highly correlated with the number of errors they make on the driving task. Participants generally score the same on each test when they take them again. It seems that the measures Dr. Lopez is using are
A) reliable and valid.
B) reliable but not valid.
C) valid but not reliable.
D) neither valid nor reliable.

Quizplus · Accepted Answer

The measures are reliable because participants generally score the same on each test when they take them again, indicating consistency. They are valid because the eyesight scores are highly correlated with the number of errors made on the driving task, showing that the tests measure what they are intended to measure (ability to recognize road signs from far away).
