Hi there and thnx for this excellent video
can you do a video on Stratified Cronbach Alpha for multi level scales !

[@bayz4918]

Thanks it is good explanation

[@sepanodebulan5789]

I managed to remove negative Cronback alpha by removing regression outliers, look at Cook Distance.

Thank you for sharing, Dr Christian!
As an alternative reliability test, what do you think about McDonald’s Omega?

[@QuantFish]

Hi Lawrance, I would use Cronbach's alpha for measures that are essentially or strictly tau-equivalent (i.e., that measure a single common factor with equal loadings). McDonald's Omega can be used when the measures are unidimensional but don't have the same loadings (congeneric measurement model). Best, Christian Geiser
