WebSep 5, 2024 · Cronbach's alpha coefficient is functionally equivalent to the third formulation listed above: the average measures consistency formulation or ICC(C,k). If you don't believe me, ask SPSS to output the two-way consistency ICCs and compare the alpha value it gives you to the average measures ICC it gives you; they will be the same. WebBelow is the formula for Cronbach’s alpha. Where: N = number of items. c̅ = mean covariance between items. v̅ = mean item variance. The calculations for Cronbach’s alpha involve taking the average covariance and dividing it by the average total variance. Therefore, a high alpha value requires the covariance to be high relative to the item ...
