Question

Quizplus · Accepted Answer

The value of coefficient alpha cannot be interpreted as "bigger is always better" or "smaller is always better." The interpretation depends on the context of the study and the scale of measurement. Generally, values of alpha between 0.7 and 0.9 are considered good, whereas values above 0.9 may indicate redundancy among items in the scale. A negative value for alpha is not possible since it is a measure of internal consistency and ranges from 0 to 1. Therefore, none of the given choices are correct.
