Cronbach’s alpha is a measure of internal consistency, that is, how closely related a set of items are as a group. It is considered to be a measure of scale reliability. A “high” value for alpha does not imply that the measure is unidimensional. If, in addition to measuring internal consistency, you wish to provide evidence that the scale[PDF]

Cronbach’s alpha can be written as a function of the number of test items and the average inter-correlation among the items. Below, for conceptual purposes, we show the formula for the Cronbach’s alpha:What does Cronbach’s alpha mean? | SPSS FAQSee all results for this questionHow do you increase Cronbach's Alpha?How do you increase Cronbach's Alpha?One can see from this formula that if you increase the number of items, you increase Cronbach’s alpha. Additionally, if the average inter-item correlation is low, alpha will be low. As the average inter-item correlation increases, Cronbach’s alpha increases as well (holding the number of items constant).What does Cronbach’s alpha mean? | SPSS FAQSee all results for this questionWhen does Cronbach's Alpha increase?When does Cronbach's Alpha increase?Cronbach's alpha generally increases when the correlations between the items increase. For this reason the coefficient is also called the internal consistency or the internal consistency reliability of the test. The value of alpha (α) may lie between negative infinity and 1. However only positive values of α make sense.Cronbach s Alpha - Measurement of Internal ConsistencySee all results for this questionFeedback
Cronbach's Alpha Basic Concepts | Real Statistics Using Excel
