Well, with the new semester I've been pretty busy.

I'm using the 32sii a lot, but I'm also getting a lot out of the 28s (especially in statistics). But I've got some issues with the RPL programming that I haven't figured out yet.

The built in stats functions include a sample standard deviation, which is great. But I really need to write a bit of code to do a population standard devation (not by adding the mean to the sumdata and redoing the sdev as is done on the 20s)

I'm - quite honestly- totally lost on this. (and then there's the rest of what I need to build- grabbing median, finding modes (with some reasonable guessing as to how many there might be), ranges, limits, and midpoints of grouped data....)

Anyone want to pop a few tidbits out so I can get to the baby step stage instead of wondering how one starts thinking about sorts, summation, and etc in RPL?
