Question

Quizplus · Accepted Answer

Internal consistency reliability is specifically designed to assess the internal consistency of a scale. It examines the extent to which items within a scale are measuring the same underlying construct. The most commonly used method for assessing internal consistency reliability is Cronbach's alpha, which is a coefficient ranging from 0 to 1 that measures the degree to which items in a scale are positively correlated with each other.
