Why not use R? [Bioanalytics]

Dear Ohlbe!

» […] using […] R to calculate the mean of 6 values would be like using a sledgehammer to kill a mosquito, and would seriously reduce the number of possible users.

Hhm, the only hurdle I see are the sometimes strange import routines. For R novices there's a nice GUI, the R Commander. Import from a text-file, the clipboard, an URL, SPSS, Minitab, Stata, Excel, Access, or dBase is just a few mouse-clicks away. You may perform fairly sophisticated statistics right there (definitely far beyond Excel's capabilities already), or simply type at the command line
sd(c(90000001, 90000002, 90000003))
[1] 1
sd(c(0.90000001, 0.90000002, 0.90000003))
[1] 1e-08

That's all - not a sledgehammer to kill a mosquito, but just a tiny pin.

See here concerning validation.

Cheers,

To propose that poor design can be corrected by subtle analysis techniques
is contrary to good scientific thinking.    Stuart J. Pocock
