Question

Quizplus · Accepted Answer

Validity coefficients range from -1.00 to +1.00 because they measure the strength and direction of the relationship between predictor and criterion variables. A coefficient of +1.00 indicates a perfect positive relationship, while a coefficient of -1.00 indicates a perfect negative relationship. A coefficient of 0.00 indicates no relationship at all. Therefore, the correct choice is D, which is the only one that includes a range of scores from -1.00 to +1.00.
