Cronbach's alpha is a measure of internal consistency, meaning how closely related a set of items are as a group. It is most appropriate for scales with multiple Likert-type items where respondents rate their level of agreement or disagreement on a consistent scale, as it assesses the coherence of the items in capturing the underlying construct.
