Question

Quizplus · Accepted Answer

Coefficient alpha (often referred to as Cronbach's alpha) and split-half reliability are both methods used to assess the internal consistency of a scale. Internal consistency refers to how well the items on a scale measure the same construct and provide consistent results. Coefficient alpha calculates the average of all possible split-half reliabilities, while split-half reliability divides the scale into two halves and correlates the scores from each half.
