What is the range of possible validity coefficients?
A)-2.00 to 2.00
B)0.00 to 1.00
C)-1.00 to 0.00
D)-1.00 to 1.00

Question

Quizplus · Accepted Answer

The range of possible validity coefficients is from -1.00 to 1.00. Validity coefficients cannot be less than -1.00 as this suggests a negative relationship between the predictor and the criterion, which is still a relationship. Similarly, they cannot be greater than 1.00 as correlations cannot exceed perfect positive correlation. Therefore, choice D is the best answer.
