Web4 dec. 2024 · Three measures of internal consistency - Kuder-Richardson Formula 20 (KR20), Cronbach's alpha (α), and person separation reliability (R) - are considered. … WebAs we know from reading our guide on Cronbach’s alpha, this result suggests that our scale demonstrates appropriate levels of internal consistency. You can also go back and try to calculate the Cronbach’s alpha for job performance. It should be .75. Hopefully from this practice, you should now be able to calculate a Cronbach’s alpha on your own.

WebBoth KR20 and Cronbach's alpha are measures of internal consistency (broadly referred to as coefficient alpha). Under ideal circumstances (e.g., no missing data, unidimensionality of items) and with binary items, KR20 and Cronbach's alpha should essentially be the same.

It is a special case of Cronbach's α, computed for dichotomous scores. It is often claimed that a high KR-20 coefficient (e.g., > 0.90) indicates a homogeneous test.
