The Manga Guide to Statistics

Right. You can get

the precise cabinet

aroval rating if

you survey every

single voter.

However, it is

unrealistic to survey

everyone. There are

t many people.

Yeah.

Definitely.

That is why only

a limited number

of randomly

selected voters

are surveyed.

S, rui? The real group that should

be surveyed is caed a population.

A group made of samples selected

from the population is caed a

sample. Those are statistical

terms.

Dad is tormenting me

by talking about hard

topics.

Yes...

Population?

Sample?

WAH!

Shock!

I am not

torment ing

you...

I quit!

This is

nonsense!

I agr.

What he is saying is...in the case

of the aroval rating of

the cabinet, the population is

a voters.

It says that the survey was

conducted with 2,000 people, so

in this case, the sample is those

2,000 people.

But that is technicay

impoible. What am I

going to do?

If poible, I want

to examine the

population...

How can I get an idea

of the population's

status? It does not

have to be strictly

precise, but it had

beer be as aurate

as poible.

That's where

statistics

comes in

handy.

Please! Please

te me more.

We, maybe

next time.
