SPSS 17 / Vista
is there a possibility to compute Confidence intervals of the median with SPSS? Thank you

I have never had the need to construct confidence limits for a median
in SPSS. Having said that, I think the approach BELOW should work. Perhaps someone who's given this more thought can either confirm that this approach is valid or offer up another approach. HTH.

In addition, with newer versions of Statistics
you can request bootstrap confidence intervals for the median in various
procedures including Frequencies.

In reply to this post by Ryan
thank you! didn't know that command
thank you also for bootstrap! (My version: v17) I suppose the bootstrapped CI is not necessarily equal on each side if data distribution is not symmetric
