Cronbach's alpha is a measure of internal consistency. In other words, it shows how closely related a set of elements is as a group. This is used as a measure of scale reliability. A high alpha value does not mean that the measure is one-dimensional. Internal consistency is usually measured using Cronbach's alpha, a statistic calculated from pairwise correlations between items.

Internal consistency is between negative infinity and 1. If the within-subject variability is greater than the between-subject variability the coefficient alpha is always negative. Cronbach's alpha measures the internal consistency or reliability of a set of survey items. Use this statistic to determine whether collections of items consistently measure the same characteristics. Cronbach's alpha quantifies the level of agreement on a standardized scale from 0 to 1.
