Question

Quizplus · Accepted Answer

Internal consistency reliability coefficients range between 0 and 1. A reliability coefficient of 0.65 suggests low internal consistency, and indicates that the items on the test may not be measuring the same construct consistently. Generally, a reliability coefficient of at least 0.70 is considered acceptable for research purposes.
