If there're four items (questions) as a group measuring the
same thing, but their reliability is only 0.3998, then what shall we do? Shall
we delete one of the items that causes the trouble? Or maybe we can do nothing
but to say that those four items are not suitable for multivariate data
analysis??
Thanks a lot! *^_^
