Question

Quizplus · Accepted Answer

Coefficient alpha (or Cronbach's Alpha) is the most appropriate way to determine reliability with Likert scales, where different answers receive different weightings. This method calculates the internal consistency of the items within the scale and provides a coefficient ranging from 0 to 1. A coefficient alpha of 0.7 or higher is typically considered acceptable for research purposes.
