Much more analytical students, but not so much good at basics that you need to make good analysis.

It’s a fairly simple concept that is used quite frequently for small subsamples. It simply improves the validity of the findings.

I actually think this is a far more interesting type of polling because it does look closely at a subgroup and their attitudes instead of just giving you a quick yes or no–I wish we did more of it because I think it teaches us a lot more about subgroups than general polling.

The 77 black respondents were kept in the “topline” of the poll, but in order to get a better understanding of what the black population in general thinks, they “re-included” the 100 in the crosstabs, because otherwise the sample would have been too small?

In any case: who cares? It’s a poll, not an election. People’s obsession with polls, particularly so far away from an election and in the middle of a primary fight, are beyond meaningless. The horse race stuff has spiraled out of control.

Wasn’t the margin of error over 7% anyway?

At least that’s what my high school math teacher friends tell me they encounter when freshmen show up knowing basic algebra but unable to understand fractions/percentages.

Morons.
