I?ve got a (maybe very simple) question:

I would like to calculate the split-half reliability (Spearman/ Brown) for a whole scala (including 14 items).
The split half reliability is a very old method now. Essentially, it depends on the split. You can think of Cronbach's alpha as the average of all possible split half reliability coefficients.
