Some of the dimmer lights in the blogosphere aren’t quite understanding the concept of oversampling for subgroups as NBC/WSJ did for the African-American sample in their latest poll.
It’s fairly simple. There is a general sample of 700 respondents with 11% African-American and 75% White respondents. Looking at their subsamples, there are 520 white respondents which is approximately 75% of the whole sample. If you read what the WSJ and Chuck Todd say is that they added 100 African-American respondents to the crosstabs–or the breakdowns by race. This means that in the general sample there are 77 African-Americans and in the smaller African-American sample there are 177 African Americans.
Before trying to discredit the poll or acting all outraged, do the math. All one needs is a basic understanding of percentages.
Furthermore, Taylor Marsh is very upset that the poll includes Republicans. I kid you not. She might read the poll results with questions from the article she linked to and notice that it only includes Democrats and likely Democratic primary voters if they identify themselves that way. But shiiiiiiiiittttt, we’d hate to read the damn thing and know something about what we are talking about.
