Hi Joel,

I think the data will be used mostly to get a feel for how people might
do in upcoming processes based on the results obtained on the test to
the present date. This data would be expected to be most useful when
the test takers in a given sample are similar to those in the
population. If they differ, the results will too.

Hi Pat,

Perhaps the answer depends on the purpose for the norms.

Can you tell us a bit more about your project?
