How many items are you summing? The value of coefficient

alpha is related to the average item covariance/correlation and

the number of items. Also, make sure the covariance/correlations

are in the same direction.

Subject: Appropriate to use Cronbach Alpha on a Yes/No scale

 

I'm attempting this and getting very low Alphas.

Is it advisable to use the measure with a 2 point scale?
