D) -2.0 to 2.0.

Question

Quizplus · Accepted Answer

The appropriate range for Cronbach's alpha is 0.0 to 1.0, where alpha values closer to 1.0 indicate higher internal consistency reliability of the measure. A value of 0.0 indicates no internal consistency reliability and a negative alpha value indicates the measure has internal inconsistency. Therefore, option A is the correct choice. Option B, C, and D are incorrect because they do not reflect the appropriate range for Cronbach's alpha.
