The money is in place,
Printing and distribution are in place,
After 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 hired Nikolic and Solomon.
Both students were confused and worried.
On the way to the office, Nikolic whispered: "I wonder what Professor Lu wants to do with us? Could it be that...hiss...could it be that you have gone too far before?"
Solomon was puzzled;
"What's too much?"
Nikolic prompted: “It’s about ‘Answer’.”
During that time, the students from the girls' school blocked the door every day, and those who didn't know it thought they were going to kidnap Professor Lu.
Solomon showed a smile that all men understand,
"Hey, you know nothing!"
Nikolic rolled his eyes;
"My roommate is French, what don't I understand?"
The conservative atmosphere in the UK has led to universities temporarily not recruiting female students. London Political Science and Economics is like a monk temple.
It's quite eye-catching to see girls from a girls' school.
Solomon said: "Don't worry, Professor Lu won't blame me for that kind of thing. I'm not sure about thanking you. On the contrary, you listed nineteen questions when Professor Lu was giving a lecture. You won't bother him by asking him questions." 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.
Students of London Political Science and Economics are proud to question Lu Shi.
If Lu Shi held a grudge because of this, he would have too many targets.
The two of them were puzzled about the purpose of their trip, so they arrived at 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 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 in layers.
There is a "whiteboard" hanging on the wall on the west side. The whiteboard is made up of wooden boards + tanned leather + white paper stacked in sequence. You can use a pencil to write and draw on it, which is much more convenient than the blackboard commonly used for teaching.
The dust accumulated in the corners of the room has not been cleaned up, and the floating tiny fibers are extremely obvious in the sunlight, floating back and forth in the air.
"Ah sneeze!"
Solomon couldn't hold it back and sneezed.
Afterwards, he covered his mouth and nose in embarrassment and said, "Sorry, Professor Lu."
Lu Shi was standing in front of the whiteboard writing something when he turned around,
"You can sit wherever you like."
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 guy!
Lu Shi chuckled,
"Relax, it's not a bad thing to come to you."
He patted the whiteboard behind him and said, "This is why I'm looking for you, public opinion 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 can be understood literally, others cannot.
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. If you want, you can try to answer them in order. Of course, it doesn't matter whether you answer or not."
Solomon reached out and took it, glanced at it and said in surprise: "Are you going to test it?"
Lu Shi shook his head,
"That's not a paper. Anyway, you read it first."
Two students began to read carefully.
1. Have you ever received a recruitment flyer?
2. Do you think military life is of great help to young people?
3. Have you considered military school?
…
a series of questions,
Only at the end did he come to a conclusion: "Do you think the country should implement conscription?"
Solomon and Nikolic looked at each other,
The two of them already knew what Lu Shi wanted to do.
Lu Shi chuckled,
"This shouldn't be difficult for you to understand, right?"
Solomon replied: "Yes, London School of Economics and Political Science students have generally conducted similar surveys. However, they are all conducted through face-to-face questions and these questions are not printed."
Lu Shi said: "What you are doing is actually a public opinion survey."
Solomon was a little confused;
"ah?"
Lu Shi wrote a word on the whiteboard——
Individual interviews.
Afterwards, he said: "Your survey method is interview. The advantage of this method is that the response rate is very high, it is not limited by the literacy level of the respondents, and 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 face to face."
Lu Shi nodded approvingly, thinking that he was not wrong about the person.
This guy can make it happen.
Lu Shi continued: "So I decided to adopt another method, the questionnaire method."
He pointed to the paper.
Nikolic scratched his head,
"This can indeed improve efficiency and reduce costs, and the anonymity effect is also very good. But the question is, will there really be so many people answering?"
Lu Shi said: "Very good, you have thought of the top priority."
He wrote two more nouns on the whiteboard——
answer rate,
Efficient.
Just looking at the literal meaning, the two words are not difficult to understand.
In fact, in addition to the response rate 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 target was only in London, and the citizens' literacy rate was extremely high, so there was no need to worry.
Lu Shi said: "Actually, the response rate is very good because the questionnaire issuer I contacted is the Royal Publishing House."
Nikolic:? ? ?
Solomon:? ? ?
The two were shocked.
How did Professor Lu say such subversive words with a calm face?
Lu Shi continued calmly: "The key is efficiency. In fact, public opinion polling itself is a business. Generally speaking, the cost of samples is very high. If there are customized requirements such as demographic attributes, region, and consumer behavior, , it will be more expensive. Let me test you, what are the problems that need to be solved here?"
Nikolic answered 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 conditions of the interviewees must meet the requirements of the survey. However, since we are discussing military conscription, it means that it should be open to all people, so this is not critical."
Lu Shi smiled,
"Wrong, it should be all male adult citizens."
What follows is self-explanatory.
Because only male adult citizens hold votes,
As for those who don’t have votes,
Sorry, I have to hold back my opinions.
Nikolic couldn't help but frown,
"Professor Lu, you just said that opinion polling is a business in itself. Could it be that...well...I'm worried that I won't be able to do it."
When Solomon heard this, he couldn't help but shake his head.
My friend is good at everything, but he is too upright.
As long as a normal person can see the influence of Professor Lu's opinion poll and be deeply involved in this project, let alone successfully graduate, I'm afraid it will be no problem to become a new star in the media industry. Why can't Nikolic be more flexible? ?
However, when his friend makes a decision, Solomon will definitely advance and retreat together.
He said: "Professor Lu, I agree with Negati."
Lu Shi did not feel dissatisfied;
"Don't worry, opinion polls are a public tool. We can't be paid to do things for others. To convince people with reason... No, it should be to convince people with data~"
What a "convincing person with data"!
Nikolic and Solomon looked at each other and apologized to Lu Shi at the same time: "Sorry, we wrongly blamed Professor Lu."
Lu Shi waved his hand and said: "It doesn't matter. In the future, I will leave the polling matter 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 lowered his head and thought,
Suddenly, he raised his head and said, "Professor Lu just mentioned 'male adult citizens'. I was wondering if I could do an article on this?"
Lu Shi laughed loudly,
"Interesting! You picked a difficult issue right from the start."
