"Come on, Jiahui," Chi Zhouxu said after shaking hands with Liu Kai, and immediately encouraged his girlfriend beside him.
"Yeah," Tang Jiahui nodded with a sweet and shy smile.
Director Tao continued to announce the names of the candidates in order of defense. "The next one is also Professor Shen's student, Tang Jiahui. Professor Shen, please give us a brief introduction."
Before each student defends their thesis, they will write a brief introduction of 300 to 200 words, including their name, date of birth, major, supervisor, honors received during their school years, as well as the scientific research projects and papers they have participated in during their studies.
After writing, hand it to the tutor. Before the defense, the tutor will briefly introduce his or her student to the experts based on the written introduction.
After Shen Qingyi finished his introduction, Tang Jiahui was already standing in front of the podium.
"Good afternoon, experts! I'm Tang Jiahui, and the topic of my defense is..."
Like Chi Zhouxu, Tang Jiahui was well prepared, and she even looked more at ease than Chi Zhouxu.
Because she was well prepared, Tang Jiahui was not asked many questions. After she stepped down, the defense experts praised her for the detail of her work and said that if it had been more in-depth, it could have been used as a doctoral thesis.
Although Zhou Mo was sitting behind Shen Qingyi and couldn't see Shen Qingyi's expression, at this moment, he knew without a doubt how proud Shen Qingyi was as a mentor.
When the master's student upstairs started his defense, Zhou Mo was extremely alert.
There is no need to say much about the PPT presentation stage. Anyone who can defend his thesis without writing two or three manuscripts and rehearsing eight or ten times will be generally quite fluent.
But even so, Zhou Mo still found some problems in his PPT.
When experts comment on questions, they usually focus on innovation and research methods, and often ignore some minor issues.
Zhou Mo turned to look for small problems like typos, irregular P-value and statistic labeling, and missing test level α...
After the experts finished their questions, Director Tao would symbolically ask everyone present, "Does anyone else have any questions?"
Zhou Mo raised his hand: "In his results section, many statistical values are not marked. Also, the three-line table is not standardized."
Everyone present was stunned.
Including the students on the stage, they reacted for a moment slowly. This kind of problem is a minor issue, probably just like making a few typos occasionally when writing an argumentative essay. It is not a big deal and does not affect the level of writing.
But since Zhou Mo raised the issue, as the respondent, he had to respond.
The student on the stage apologized, "Thank you for pointing out the problem, it's true that I didn't do it carefully. I will correct it when I get back."
Those who came on stage after him were even more nervous. In such an occasion, who wouldn't be nervous when meeting someone as picky as Zhou Mo?
Perhaps it was because the students upstairs did not have the style of Shen Qingyi's group, who modified the PPT word by word, and only focused on the general context and the final presentation of the results. The subsequent students really had all kinds of small problems.
In the end, Zhou Mo actually found a more serious problem.
"Your chi-square value is so small, can you conclude that P is less than 0.05?" Zhou Mo looked at him and felt something was wrong.
The student on the stage said nervously, "This is what I calculated."
Zhou Mo's attentiveness also drew the attention of other experts to this issue. Professor Yuan pointed to that page of PPT and said, "You are absolutely wrong. Let me ask you, what distribution is the chi-square test based on? Think carefully about what its distribution function curve looks like, and then answer."
The students on the stage were completely frozen.
"I, I... Professor Yuan... I'll go down and take a look." The student could only use the universal answer killer "Go down and take a look."
Professor Yuan was very dissatisfied and glared at him. "Although we are not professional mathematicians, which of the methods we use is not from statistics? If you don't understand such basic principles, how can you apply them? Are your results true? Are they fabricated?"
When these words were spoken, everyone present was shocked.
Falsifying scientific research papers is a taboo, including now. Even if you graduate with a master's or doctoral degree, if problems are discovered in your thesis one day in the future, your degree will still be revoked.
"No, Professor Yuan, definitely not." The student on the stage was anxious and at a loss, and could only look at his instructor.
It was his tutor who answered his questions and helped him out of the predicament, and the matter was finally resolved.
After him, Professor Yuan would ask some basic questions to every student who came. They all came from a medical background and did not have a strong mathematical background. The projects they did were also imitations of others. They used the same methods as others and never delved into why they used these methods.
Due to the long-term inertia of thinking and superficial understanding, everyone was dumbfounded and unable to answer the very basic statistical questions raised by Professor Yuan.
Professor Yuan's expression became increasingly grim, and his questions became increasingly intractable. By the time it was the doctoral student's turn, the questioning session had stretched from twenty minutes to more than half an hour.
People were in panic throughout the whole process.
The further back you get, the greater the psychological pressure.
Even the initial friendly expressions on the faces of the instructors were gone, and instead everyone looked worried.
Tang Jiahui pulled Zhou Mo aside and whispered, "Luckily, Xiaochi and I talked about this early. If I had been in the back of the queue, I would have been scared to death."
Zhou Mo smiled and said nothing.
After all the students finished their defense, everyone except the defense experts was dismissed.
After half an hour of discussion, everyone passed the defense qualification without any surprise.
The students were relieved, but the instructors were not.
Director Tao called the tutors away individually and said he wanted to hold a small meeting, and Professor Yuan was also attending the meeting.
Needless to say, everyone knows that the problems exposed in this defense are serious and the tutors are going to be criticized.
If the tutors don't have an easy time, the students won't have an easy time either.
Zhou Mo took everyone to clean up the meeting room after the defense.
The students upstairs also cleaned up together with little interest.
Some people complained, "What's all this? I bought so many things, but the experts didn't even look at me kindly. I bought so much for nothing."
"Well, wait, when the teacher comes back from the meeting, we'll get scolded again."
"I've spent a lot of money and received a lot of criticism, but this defense is... just full of frustration."
Almost all the students upstairs took out their frustrations about their unsuccessful defenses on the table full of "feast".
There was even an angry doctor who threw a rag on the table and said, "Where's Ren Huaibo? He's got so many useless things. It seems like he's just wasting the money since it's not his, right?"
Chi Zhouxu was about to speak when Zhou Mo stopped him, shook his head slightly, and signaled him not to get involved.
Ren Huaibo had just come back from taking out the trash. As soon as he entered the door, he was blocked by several people who asked about the use of the funds for this defense.
The students raised 30,000 yuan in funding, but spent nearly 10,000 yuan just on preparing the defense venue, including food, drinks, and flower arrangements.
Not to mention that the experts' defense fees have not yet been settled.
