What is it like to go to college?

Yoo Jimin had a pair of round-framed glasses on her face that didn't belong to her, and her right hand was supporting her chin, only to feel that her eyelids were fighting and getting heavier and heavier.

These glasses have no prescription, but the lenses that have been specially crafted are said to filter out blue light, so you won't feel overly tired even if you look at the screen for a long time.

This pair of round-framed glasses was worn on Wen Yingheng's face, like a mature and intellectual senior, and a little more scholarly.

Worn on Yoo Jimin's face...... The first word that Wen Yingheng thought of was - little mom literature.

Put your hair down, it's a young girl with a little cuteness, and when you put your hair up, it's completely ...... It's too foul.

Wen Yingheng could only try to shift his attention to the courseware he had prepared.

"Interval estimate is an interval range of population parameter estimation based on point estimate, which is usually obtained by adding or subtracting the estimation error from the sample statistic......"

"In interval estimation, the estimation interval of the population parameter constructed from the boilerplate statistic is called the confidence interval......"

What kind of alien terms is he talking about...... Yoo Jimin endured the sleepiness and tried hard to listen to what Moon Young-heng said.

It's just that for her, whose math foundation is still in high school, these things are completely superclass.

If you have insomnia in the future, you must find Wen Yingheng to give you a lecture. But...... It seems that as long as Wen Yingheng is by her side, her sleep quality is already very good, and he doesn't need to say anything?

Liu Zhimin's mind has a lot of things, but it can't fit the knowledge that Wen Yingheng said.

"Next is the data I crawled on the Internet, which is the personal information disclosed by the members of the aespa fan station, including gender, age, occupation and other factors, you can go back and download these data according to the steps I said, and use the knowledge taught today to analyze the relationship between the factors involved in the personal information and the fan level."

"This data is anonymized, if you have any questions, you are welcome to contact me in a private message......"

Suddenly hearing the name of aespa, Yoo Jimin, who was sleepy, suddenly came to his senses, and the eyes that originally looked at Wen Yingheng also brightened.

After finishing the recording of this class, Wen Yingheng looked at the girl who was listening to the class very attentively - in fact, it was nothing for her to sleep for a while, and holding on like this made Wen Yingheng feel guilty.

"Nothing...... Hey. ”

He didn't have a lot of confidence in the recorded lessons, after all, the whole series was only three hours, and it was designed to take students through the various knowledge points of "Statistics" in a relatively short period of time, and help those students who needed to cram on a temporary basis...... At least you can get a passable score in the final assessment.

The main reason is that he is busy at the end of the semester, so it is impossible to explain the knowledge points in too detail, which is also what he is not very satisfied with this series of courses.

If you have time in the future, you must re-sort out these knowledge points, record them into a more systematic course, and upload them to the Internet again.

"Am I not speaking well?" Wen Yingheng glanced at the video that had been recorded with some weakness.

"I don't understand what you're talking about...... But I think the class would be interesting if aespa was cited as an example. Yoo Jimin snorted with satisfaction and opened the data that Moon Young-heng had saved on the desktop.

When was he...... What is this fan data collected?

The change history of this document shows that the last time this document was revised was in September 2022.

It turns out that this guy has been paying attention to aespa.

"I made all this data with my fingertips." Wen Yingheng pretended to be very relaxed: "You know, to be in our industry, you have to understand some data collection methods, and I happen to know some reptile skills......"

Duduplicity, if that's the case, why do you have to explain so much?

"Oh, got it."

Yoo Jimin's seemingly bland reply made Moon Yingheng feel like a fist hit the cotton.

In order to take care of Wen Yingheng's face, Liu Zhimin turned his head sideways and rubbed Wen Yingheng's shoulder with his hair: "I'm really interested in the data you said...... Can you teach me? ”

…………

"Lower Confidence Bound, Upper Confidence Bound...... α errors, β errors...... Earthy love story ......"

Yoo Jimin sat on the sofa in the aespa dormitory, only to feel that countless incomprehensible statistical terms were swelling in his head, occupying the entire screen like a barrage, and occasionally a few different barrages popped out were the earthy love words that Moon Yingheng had just said.

"Ernie, what are you muttering?" Ning Yizhuo put down his phone, his eyes showing worry.

Yoo Jimin, with fluffy hair and even a little messy, pushed the frame, and the lenses reflected a little white light in the light of the dormitory light.

"It's nothing, it just feels like my brain is overactive and strained......"

Remembering half an hour ago, the third hour that Moon Young-heng taught her statistics, Yoo felt that she had made up for all the math lessons she had missed in the past few years.

“Stop！ Get here today! The girl took her sweatshirt and hat with her, and lay down on her desk completely exhausted, her right face against the tabletop, and her pupils were much less shiny.

In the past, when the two were separated in Seoul and Los Angeles, Yoo Jimin often listened to Moon Young-heng share his learning troubles, and he only felt that he was hypocritical...... But when he really started to learn some of the basics he was going to learn at the beginning, Liu Zhimin was hit by the huge gap between people.

It is said that no one is perfect...... So what is Wen Yingheng not good at? With such doubts, Yoo Jimin couldn't help but feel a little depressed.

"What are the shortcomings of you? People shouldn't be without shortcomings......"

"Are you interested in this question?" Deliberately fishing for Liu Zhimin's appetite, Wen Yingheng snapped his fingers and said: "As soon as you say this, I just realized that I have a lot of advantages, I cook well, my appearance is passable, my sports grades are okay, and I have gone further than others in terms of learning." As for my shortcomings......"

"Fault you."

Yoo Jimin's eyes widened slightly, and only after his brain responded for two seconds did he let out a strange "ah", and his two hands slapped Wen Yingheng's arm at an extremely high frequency.

"The flesh is numb, the flesh is numb...... Well, why do you have to talk about earthy love words. ”

"Then I won't talk about it in the future?"

"Ahem...... But I also like to listen to it occasionally. But in return for today, these glasses of yours belong to me first. ”

Ning Yizhuo, who still couldn't let go of his heart, took the initiative to sit down and helped Liu Zhimin knead his temples: "Is this better?" ”

Still immersed in memories, Yoo Jimin nodded blankly, and then quickly shook his head: "I decided ......"

"What has been decided?"

"If you want to help your child with their homework in the future...... This responsibility should be completely handed over to Wen Yingheng. ”

Ning Yizhuo, who was suddenly fed a mouthful of dog food: "6......"
