Thank you We sneak And here's your smoke du jour

00:06

brought to you by a demographic model the most representative

00:09

of all fashion icons All right what sort of pole

00:13

begins by building a demographic model and here the potential

00:16

answers them x entering quota Okay no demographic models aren't

00:22

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
