the best looking of all poles but what they do
- 00:25
is allow us to hone in on a specific segment
- 00:28
of the population and find out what makes them tick
- 00:31
Random sample polls are well random by definition since we
- 00:35
want to reach a wide a sample of people as
- 00:37
possible to answer our questions So we wouldn't want to
- 00:40
build any kind of model for that Exit polls which
- 00:43
take place right after people have voted in an election
- 00:46
can certainly be broken down by demographic But that's something
- 00:48
we would do after we collect the data not before
- 00:54
Tracking polls which are used to monitor changes over time
- 00:56
Our helpful for determining the shifting moods of say parents
- 01:00
going through a mid life crisis But we wouldn't necessarily
- 01:03
need a demographic model to model those changes Often poles
- 01:07
like those has he internet pop up questionnaires require individuals
- 01:11
to choose to be part of the survey so it
- 01:13
would be pretty useless to build a model when we
- 01:16
have no control over who participates quote a sample polls
- 01:19
air used tto find out the opinions of a certain
- 01:21
segment so we'd start by building a model of the
- 01:24
group were interested in say women between the ages of
- 01:26
eighteen and thirty five and then we look for a
- 01:29
random sample of respondents in that particular category So the
- 01:32
correct answer here is e quote a sample Polls are
- 01:35
not designed to be representative of the broader population So
- 01:38
if you wanted to do a pull of men named
- 01:40
william well you'd build out your model and solicit participants 00:01:43.955 --> [endTime] who fit the bill
