printing and distribution,

Traveling to England in 1900 for more than two months, Lu Shi was finally able to do some "serious" things.

He asked Bernard Shaw for an office and brought in Nikolic and Solomon.

The two students were quite confused and worried.

On the way to the office, Nikolic said in a low voice, "I don't know what Professor Lu is looking for us for? Could it be... hiss... Could it be that you have done too much before?"

Solomon was puzzled,

"What is too much?"

Nikolic reminded: "It's about "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 showed a smile that any man could understand,

"Hey, you know what a fart!"

Nikolic rolled his eyes,

"My roommate is French, what do I not understand?"

The conservative atmosphere in the UK has led to the temporary exclusion of girls from universities, and LSE is a temple for monks.

It is still very seductive 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'm not sure. On the contrary, you listed nineteen questions in Professor Lu's lecture before, and you won't bother him. Alright."

Nikolic shook his head,

"Professor Lu is rigorous in his studies and even encourages us to question him a lot. How could he be that kind of person?"

That's right.

LSE students are proud to question Lu Shi,

If Lu Shi held grudges because of this, then there would be too many targets.

The two of them couldn't understand the purpose of this trip, so they arrived in front of the office door in a daze and knocked on the door.

Lu Shi's voice immediately came from inside,

"The door is unlocked, just go in."

The two pushed the door open and entered.

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

Close to the wall on the east side, several sets of tables and chairs are placed in layers,

On the wall on the west side is a "whiteboard". The whiteboard is assembled by stacking wooden boards + tanned leather + white paper in sequence. You can write and draw on it with a pencil, which is much more convenient than the general blackboard for teaching.

The dust accumulated in the corners of the room has not been cleaned, and the floating fine fibers are extremely obvious in the sunlight, floating back and forth in the air.

"Ah Choo!"

Solomon couldn't hold back and sneezed,

After that, he covered his nose and mouth in embarrassment and said, "Sorry, Professor Lu."

Lu Shi was standing in front of the whiteboard and writing something, turning around,

"Sit down wherever you want."

Nikolic and Solomon stood still, not daring to move.

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

Nikolic gave Solomon a hard look,

I knew it was this product!

Lu Shi chuckled,

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

He patted the whiteboard behind him and said, "That's what I'm looking for, polls."

Two students subconsciously looked at the whiteboard.

I saw many nouns with unclear meanings written on it:

polls,

sampling,

sample size,

...

Some words are taken literally and some words are not.

Lu Shi also knew that it would be 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 it one by one. Of course, it doesn't matter if you answer or not."

Solomon reached out to take it, glanced at it and said in surprise, "Are you going to test it?"

Lu Shi shook his head,

"That's not a test paper. Anyway, read it first."

Two students began to read carefully.

1. Have you ever received a conscription leaflet?

2. Do you think military life is of great help to young people?

3. Have you considered military school?

...

a series of questions,

It was only at the end that he asked: "Do you think the country should implement conscription?"

Solomon and Nikolic looked at each other,

The two already knew what Lu Shi wanted to do.

Lu Shi chuckled,

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

Solomon replied: "Yes, LSE students have generally done similar surveys. It's just that they asked questions face to face and didn't print out the questions."

Lu Shi said, "What you do is actually a public opinion survey."

Solomon was a little confused,

"ah?"

Lu Shi wrote a word on the whiteboard——

Individual interviews.

After that, he said: "Your survey 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, so it has wide adaptability. But relatively, the efficiency is ridiculously low."

Solomon pondered for a moment and said, "Another point is that the low degree of anonymity will affect the answers 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 did not misunderstand the person.

This lad can get things done.

Lu Shi continued: "So I decided to adopt another method, the questionnaire method."

He pointed to the paper.

Nikolic scratched his head,

"It does increase efficiency, reduce costs, and it works very well with anonymity. But the question is, will there really be that many people answering?"

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

He wrote down two more nouns on the whiteboard——

response rate,

Efficient.

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

In fact, apart from the rate of completion and efficiency, there is another point to take into consideration, which is the educational level of the subjects. For illiterate and semi-literate people, the questionnaire is definitely not applicable.

Fortunately, Lu Shi's goal is only in London, and the literacy rate of the citizens is extremely high, so don't worry.

Lu Shi said: "Actually, the response rate is easy to say, 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 say such subversive words with a flat face?

However, Lu Shi continued calmly: "The key is efficiency. In fact, public opinion surveys are a business in themselves. Generally speaking, the cost of samples is very high. If there are customization requirements such as demographic attributes, regions, and consumption behaviors, , it will be more expensive. Let me test you, what problems need to be solved here?"

Nikolic responded quickly: "The interviewee must be a real person."

Lu Shi nodded,

"That's right."

He wrote the word "real" on the whiteboard, and then said: "Continue."

Solomon said: "The qualifications of the interviewees must meet the requirements of the research. However, since the discussion is about conscription, it means that it should be open to the entire population, so this is not critical."

Lu Shi smiled,

"Wrong, it should be all male adult citizens."

The words behind speak for themselves.

Because only male adult citizens hold votes,

As for those without votes,

Sorry, I have to hold back my opinions.

Nikolic could not help frowning,

"Professor Lu, you just said that polling itself is a business. Could it be that... well... I'm worried that I won't be able to do it."

Solomon shook his head when he heard this.

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

As long as they are normal people, they can see the influence of Professor Lu's opinion survey, and can deeply participate in this project. Not to mention graduating smoothly, I am afraid that there is no problem in becoming a new star in the media industry. Why can't Nikolic be more flexible? ?

However, when his friend made a decision, Solomon would definitely advance and retreat together.

He said, "Professor Lu, I agree with Nicati."

Lu Shi didn't think it was disobedient,

"Don't worry, polls are public tools, we can't do things for people by collecting money. Convince people with reasoning... no, it should be convincing people with data~"

What a "convincing people with data"!

Nikolic and Solomon looked at each other, and apologized to Lu Shi at the same time: "Sorry, we were wrong to blame Professor Lu."

Lu Shi waved his hand and said: "It's okay. In the future, I will hand over the polls to you, but you are not experienced enough now, so I will take you to do the first set of questionnaires. Do you have any issues that you are particularly concerned about? "

Nikolic bowed his head in thought,

Suddenly, he raised his head and said, "Professor Lu just mentioned 'male adult citizens'. I thought, can we make an article on this?"

Lu Shi laughed loudly,

"Interesting! You picked a difficult topic right from the start."
