Money in place,

Printing and distribution in place,

After more than two months in England in 1900, Lu Shi was finally able to do something "serious".

He asked George Bernard Shaw for an office and summoned Nikolic and Solomon.

Both students were confused and worried.

On the way to the office, Nikolic whispered, "I wonder what Professor Lu is looking for us to do?" Could it be ...... Hiss...... Could it be that you have gone too far before? ”

Solomon was puzzled,

"What's too much?"

Nikolic prompted: "It's the matter of the Answer." ”

During that time, the students of those girls' schools blocked the door every day, and those who didn't know thought they were going to kidnap Professor Lu.

Solomon smiled in the same way that all men know,

"Hey, you know a!"

Nikolic rolled his eyes,

"My roommate is French, what don't I understand?"

The conservative atmosphere in Britain has led to the temporary closure of universities to admit female students, and London Politics and Economics is a monk's temple.

It's still very eye-catching to see the girls in the girls' school.

Solomon said, "Don't worry, Professor Lu won't blame me for that kind of thing, thank you I don't have to." On the contrary, it was you, who listed nineteen questions when Professor Lu was lecturing before, so it wouldn't be annoying to ask him. ”

Nikolić shook his head,

"Professor Lu is rigorous in his studies, and even encourages us to question him more, how can he be the kind of person with a small belly?"

That's right.

London students of economics and politics are proud to question Lu Shi,

If Lu Shi holds a grudge because of this, then there are too many targets.

The two of them were puzzled by the purpose of this trip, and they went to the office door in a daze and knocked on the door.

Immediately, Lu Shi's voice came from inside,

"The door is unlocked, just go in."

The two pushed the door open.

This office was obviously temporarily allocated to Lu Shi, and it should have been used as a storage room before.

Close to the east wall, several sets of tables and chairs are placed on top of each other.

On the west side of the wall, there is a "whiteboard", which is stacked and assembled by stacking wooden boards + tanned leather + white paper in turn, and can be written and drawn with a pencil, which is much more convenient than the blackboard used for general teaching.

The dust in the corners of the room had not yet been cleaned, and the floating fine fibers were unusually noticeable in the sunlight, wafting back and forth in the air.

"Ahh

Solomon did not hold back, and sneezed,

After that, he covered his mouth and nose embarrassedly and said, "I'm sorry, Professor Lu. ”

Lu Shi was standing in front of the whiteboard at this time writing something, and turned around,

"Sit as you please."

Nikolić and Solomon stood honestly and did not dare to move.

Lu Shi didn't care, and directly started the topic: "I heard that you are very active in school, especially Solomon, and it seems that you are very popular with other students......"

Nikolić glared at Solomon fiercely,

I knew it was this thing!

Lu Shi chuckled,

"Relax, it's not a bad thing to come to you."

He patted the whiteboard behind him and said, "This is the purpose of my approach, polls." ”

The two students subconsciously looked at the whiteboard.

I saw a lot of nouns of unknown meaning written on it:

Polls

sampling

sample size,

……

Some words are literal, others are not.

Lu Shi also knew that it was a little difficult to explain, so he took out a piece of paper, handed it over, and said at the same time: "Look at this thing." If you want, you can answer them one after the other. Of course, it doesn't matter if you don't answer or not. ”

Solomon stretched out his hand to take it, glanced at it, and said in surprise, "Is it to be tested?" ”

Lu Shi shook his head,

"That's not a roll. Anyway, you guys look first. ”

Two students began to read carefully.

1. Have you ever received a recruitment flyer?

2. Do you think military life is very helpful to young people?

3. Have you considered a military school?

……

A series of questions,

In the end, he was asked: "Do you think the country should implement conscription?" ”

Solomon and Nikolici looked at each other,

The two already knew what Lu Shi wanted to do.

Lu Shi chuckled,

"This shouldn't be difficult to understand for you, right?"

Solomon replied, "Yes, it is common for students of London economics to do similar surveys. It's just that they were all asked in person, and these questions were not printed. ”

Lu Shi said: "What you are doing is actually a public opinion poll. ”

Solomon was a little confused,

"Huh?"

Lu Shi wrote a word on the whiteboard -

Individual interviews.

Afterward, he said, "Your investigative method is interviews. The advantage of this method is that the response rate is very high, and it is not limited by the literacy level of the respondents, and it is more adaptable. But comparatively, the efficiency is ridiculously low. ”

Solomon pondered for a moment and said, "There is another point, the low level of anonymity will affect the answer to some sensitive questions. After all, some questions are really inappropriate to ask in person. ”

Lu Shi nodded approvingly, and said in his heart that he didn't see the wrong person,

This young man can do it.

Lu Shi continued: "So I decided to take another way, the questionnaire method. ”

He pointed to the paper.

Nikolic scratched his head,

"It's really more efficient, it's cheaper, and the anonymity is really good. But the question is, will there really be so many people answering? ”

Lu Shi said: "Very good, you have thought of the most important thing. ”

He wrote two more nouns on the whiteboard—

Response rate,

Efficient.

Just looking at the words, two words are not difficult to understand.

In fact, in addition to the response rate and efficiency, there is another point to take into account, that is, the cultural level of the subjects, for illiterate and semi-literate, the questionnaire is definitely not applicable,

Fortunately, Lu Shi's target is only in London, and the citizen literacy rate is extremely high, so there is no need to worry.

Lu Shi said: "Actually, the response rate is very good, because the publisher of the questionnaire I contacted is the Royal Publishing Bureau. ”

Nikolic: ???

Solomon: ???

The two were shocked.

How did Professor Lu manage to utter such subversive words with a flat face?

Lu Shi continued indifferently: "The key is efficiency. In fact, polling is a business in itself. Generally speaking, the cost of the sample is very high, and it will be more expensive if there are customized requirements such as demographic attributes, regions, and consumption behaviors. I'm going to test you, what are the problems to be solved here? ”

Nikolić replied: "The interviewee has to be a real person." ”

Lu Shi nodded,

"That's right."

He wrote the word "true" on the whiteboard and said, "Go on." ”

"Respondents need to be eligible for the survey," Solomon said. However, since we are talking about conscription, that is, it should be aimed at the whole people, so this is not critical. ”

Lu Shi smiled,

"No, it should be all male adult citizens."

The latter words speak for themselves.

Because only male adult citizens hold the ballots,

As for those who don't have votes,

I'm sorry, I have to hold back my opinions.

Nikolić couldn't help frowning,

"Professor Lu, you just said that polls are a business in themselves, do you mean...... Not...... I'm afraid I won't be able to do it. ”

When Solomon heard this, he shook his head,

Friends are good at everything, but they are too upright.

As long as you are a normal person, you can see the influence of Professor Lu's poll, and you can be deeply involved in this project, let alone graduate successfully, I am afraid that there is no problem in becoming a new star in the media industry, why can't Nikolic be a little more flexible?

However, when his friend made a decision, Solomon was bound to go with him.

He said, "Professor Lu, I agree with Nigati. ”

Lu Shi didn't think it was angry,

"Don't worry, public opinion polls are public instruments, and we can't do the work of collecting money to help people. Reasoning...... No, it should be convincing people with data~"

What a "convince people with data"!

Nikolic and Solomon looked at each other and apologized to Lu Shi at the same time: "I'm sorry, we blamed Professor Lu for it." ”

Lu Shi waved his hand and said, "It's okay." In the future, I will leave the poll to you, but you are inexperienced now, so I will take you to do the first set of questionnaires, do you have any special issues of concern? ”

Nikolic bowed his head in contemplation,

Suddenly, he raised his head and said, "Professor Lu just talked about 'male adult citizens', I thought, can you make an article about this?" ”

Lu Shi laughed,

"Interesting! You came up with a difficult topic. ”
