What difference does it make how many you're testing? By breaking the
sample into groups, you're just creating extra work. Are you going to
compare the data by age group? Why would you do that? The only reason
I can think of is if you're creating different sites. You're not.

Out of interest how many participants are you testing with? Could
you break the numbers down?

Thanks for the prompt, Jared. There's no reason to limit the age
range *at all.* As long as the behaviors are the same -- that is,
the task goals of the users -- across age ranges, then it doesn't
matter a bit how old the participants are.
As members of UPA, people over 65 would very likely have the same
tasks and goals in mind as someone younger: Maintain membership
information, renew memberships, find out what's going on in the
association, get in the consulting directory, find out who is on the
board, find out where the conference is, etc.
Limiting the age range wouldn't benefit the research. In fact,
limiting may be a detriment.

So? Why limit the age range? How does that benefit the research?

Perhaps because the core audience isn't older than 65? Not to say
that there aren't any, but I'd imagine, based on the meetings and
conferences that I've been to, that the number of people over 65 are
statistically quite small.

May I ask why the age range limits to 65?
