Quizplus · Accepted Answer

Cronbach's alpha is a commonly used correlation-based statistic to determine the internal reliability of a scale or test. It reflects the extent to which the items on a scale or test consistently measure the same construct. The values of Cronbach's alpha range from 0 to 1, with higher values indicating greater internal consistency among the items. Therefore, option A is the best choice for determining internal reliability.
