For the last 30+ days, I've been randomly taking vitamin D before bed and recording sleep data with Zeo as well as my best guess whether it was D or placebo: http://www.gwern.net/Zeo#vitamin-d

But I'm going to finish within the next <10 days, and then it's time for analysis. I would like to do a real statistical analysis, like a 'one-tailed T test', on the ZQ and components like length of REM sleep, but I don't actually know how - I've never used the standard statistical programs or packages like R. (Yes, yes, I know, I should learn real statistics. I haven't yet, though.)

My needs aren't too complex, I'm just asking whether the vitamin D did anything (bad), so maybe there is an easy to use online tool or something which would handle it?

Badger's solution works, but an alternative is to post a link to the data here and let LW take a crack at it. I can fit a wide variety of models in a matter of minutes in R, and wouldn't mind spending an hour or two doing so and writing up the results.

Well, I usually include an export of my Zeo CSV data for anyone to look at (not that anyone apparently has for the earlier bigger melatonin data), and I was going to link the results here in an open thread or something.
