It’s quite
PLAUSIBLE
that the sample was
QUITE, VERY REPRESENTATIVE of the whole.
It’s not the size per se that’s an issue . . . as I suspect you know.
It’s HOW REPRESENTATIVE was the sample, of the whole.
It may well have been very representative.
It may well have been very UNrepresentative.
Hard to tell.
Duh!
Being a non-random sample reported anecdotally by a biased source, it is impossible to tell.
