Did you know?
WebIf the variables are dichotomous (0,1), the coefficient alpha is equivalent to the Kuder-Richardson 20 (KR-20) reliability measure. When the correlation between each pair of variables is 1, the coefficient alpha has a maximum value of 1. With negative correlations between some variables, the coefficient alpha can have a value less than 0. WebAug 23, 2024 · In this case you should use standardized alpha. The second case is unusual, and so you usually use alpha (not standardized alpha). In addition, items usually have similar variances to start with, so the differences between alpha and standardized alpha are (usually) small.
