Quizplus · Accepted Answer

Cronbach's alpha is a measure of internal consistency reliability, which assesses the degree to which items in the measure are interrelated and measuring the same construct. Therefore, the best choice is B, internal consistency. The other options, such as test-retest, alternate forms, and split-half reliability, are other types of reliability that assess different aspects of the measure's consistency over time or across different versions.
