In the 2008 presidential primary, nearly every poll showed
that Barack Obama would win New Hampshire. The polls
used random-digit dialers to call a random sample of New
Hampshire households. However, many college students
came out in support of Hillary Clinton, who ended up winning
the primary.
Which of the following types of bias affected the conclusions
the polls drew?
Deliberate bias
Non-response bias
Selection bias
Response bias
RATIONALE
,Selection bias refers to a mechanism where selection of the
sample produces a sample that is not representative. The use
of random digit dialers will not capture people with private
numbers, don't have a phone, etc. So, using this selection
mechanism might produce a selection bias for the sample.

A binomial question is __________ an open question. A
closed question is __________ a binomial question.
never; sometimes
never; always
always; sometimes
always; never
RATIONALE
A binomial has only two responses. Since there are only two
responses that can occur, it is by definition a closed question
and is not considered an open question. Closed questions
don't need to only have two responses. So, only closed
questions with two responses are binomial, but they could have
more than two responses.
