Quizplus · Accepted Answer

Cronbach's alpha is a measure of internal consistency reliability, which examines how closely related a set of items or questions are as a group. It is used to evaluate the degree to which items in a scale or measure are measuring the same construct, with values ranging from 0 to 1. Higher values indicate greater internal consistency reliability.
