Yes. As mentioned before, however, I'm not interested in the complete analysis but only in reproducing the bar diagram. Note that the printed SPSS report doesn't ever mention a CI value; it is only used for the error bar in the diagram – which are huge in this particular case, BTW. I hope it is safe to assume that the error bars can be approximated by the simplest approach (i.e., based on a model for few samples) in case SPSS uses different values. So: Is there a command in PSPP that directly gives me a standard CI value? Or does I have to cook it up using the formula already mentioned in this thread?
