Fortunately, there's no money involved. :-)

As for the other caveats below, this is exactly why I asked for a volunteer with experience in statistical analysis. I'm assuming that my own analysis would be not only unqualified, but probably biased as well.

So far, there are three exclusions that will be described clearly in the final report. The volunteer statistician might question any of those exclusions or might suggest making additional ones.

While we are caveatating...
- Fallacy of assigning causes to the observed coincidences (false correlation).
- Sample size problems even when it looks like there aren't any.
- Lumping incommensurables together to create a decently sized sample set.
- Selection of data by unidentified causes.

In some agenda-driven studies (for instance, funded to provide a particular result) outliers or data that is "obviously bad" are eliminated. This has the result of sharpening a peak (reducing standard deviation), or even creating a peak where none previously existed. In extreme cases researchers might ignore a bimodal distribution. Fortunately we are all too smart to fall into any of those blunders.
