Thanks Spencer! That's what I was looking for. My data are not at all normal and neither are the transformed values because The majority are at an upper limit that is not 1 (these are grouped data abstracted from a paper). There's nothing that can be done about that, but it was good to compare the CIs for the original and back-transformed values. The SD for the transformed disitribution was huge compared to the one from the original values, though. Is this normal?
