$$ \alpha = \frac$ is the average inter-item covariance among the items and Below, for conceptual purposes, we show the formula for Technically speaking, Cronbach’s alpha is notĪ statistical test – it is a coefficient of reliability (or consistency).Īs a function of the number of test items and the average inter-correlationĪmong the items. Exploratory factorĪnalysis is one method of checking dimensionality. Unidimensional, additional analyses can be performed. Internal consistency, you wish to provide evidence that the scale in question is A “high” value for alphaĭoes not imply that the measure is unidimensional. Cronbach’s alpha is a measure of internal consistency, that is, how closely
