cronbach's alpha

How is Cronbach's Alpha Calculated?

Cronbach's alpha is calculated based on the average inter-item correlation and the number of items in the test. The formula is:
\[ \alpha = \frac{N \cdot \bar{c}}{\bar{v} + (N-1) \cdot \bar{c}} \]
where N is the number of items, \( \bar{c} \) is the average covariance between item-pairs, and \( \bar{v} \) is the average variance of each item. This formula provides a straightforward way to quantify the internal consistency of a set of items.
