Then maybe you can enlighten me as to the difference between a poll that quotes the results of a subset of x number of participants versus a poll that contacts and prequalifies the same total number of participants, but only surveys that X number that fit the general poll’s subset.
Your profession regularly quotes the responses of the 12% of African-Americans in a poll, for example, and then presents that data as if it has the same validity as the poll overall.
But I do not endorse about 75% of the “profession” - which doesn’t change my original statement…that 833 is a tiny sample for a national poll….and that a “subset” is only a subset when it’s a subset…..and when the subset is the entire set, it’s not a subset anymore.
Two concepts you can’t wrap around….
