Hi there,

I am facing the same problem.

I already tried to use Guttman and Split Half, but this statement "The determinant of the covariance matrix is zero or approximately zero. Statistics based on its inverse matrix cannot be computed and they are displayed as system missing values." still there.

I have analyzed 73 respondents with 23 variables.

If possible, I do appreciate any advices from anyone.

Can I still use Cronbach's Alpha to state that my survey was reliable?

Thank you so much.

Cheers,
Riduan
