I'm interested in this question too and hope there will be more
comments. It is almost like we are not sure what to do on those rare
occasions when we do have the whole population. Also, even when we
do try to have the whole population, people are usually missing for
some reason, e.g. refusal to participate. But, such people are
probably missing on a non-random basic, so significance tests
probably aren't appropriate in such cases either.
