Hey, doesn't that make me (and my fellow 46ers) a mode - that most
underused of statistical averages?
:-)
Talking of normal (?) isn't it about time someone dragged out the
central limit theorem? I'm guessing our sample size is too small, or
that the obvious non-independence would have an overriding effect.
OK, I didn't really want to get into this, but there are obviously many
factors that could skew the distribution of ages of the subscribers to a
newsgroup such as this; not to mention the fact that all of these
numbers are: a) self-reported, and b) not verifiable. Either of these
renders this study unreliable.
Given that, and speaking as a Zuikoholic, I'm prepared to accept that
the ages as submitted are accurate and honest. So, what do we have? A
bunch of folks who are interested in (talking about) Olympus cameras.
What do we know about the distribution of such people? With (to date) 89
replies to the age list, it's quite clear that it's not representative
of Olympus (or even OM-*) camera afficionados worldwide. So what are we
showing here? It seems to me that we're just a bunch of like-minded
souls with a common interest who have happened to have found each other
through the wonders of the Internet.
And there's nothing wrong with that.

PS - Thanks for the statistics Bernard - please keep them up!
