Chapter 4: On the Importance of Handwashing in the Sweepstakes
Bai Ye looked at the notebook and gestured: "Can I take a look?"
Xu Yan nodded and shrugged to show that it didn't matter.
Bai Ye took the notebook, opened the first page of the paper, and read it from beginning to end.
The title of the paper is "Clinical Study of Tongqiao Huoxue Granules on Chronic Cerebral Ischemia". It is an observation of a clinical case. There are three test groups. The first is the blank control group, the second group is the test group using Tongqiao Huoxue Granules, and the third
The third group used the commonly used patent medicine Shuxuetong.
However, Xu Yan observed many indicators, including serum homocysteine, blood lipids, blood viscosity, cranial MRI, and transcranial Doppler ultrasound.
It is indeed a bit difficult to conduct multiple comparisons before and after the experiment.
Bai Ye said: "Actually, senior sister, if you compare serum homocysteine, I think the data can be divided into grades. According to what you mean, it is divided into 4 grades. You can use the chi-square test or the rank sum test.
To determine...if it's blood lipids and blood viscosity, I think the t test is also acceptable..."
Bai Ye talked a lot, and Xu Yan seemed to have a sudden realization, but still shook his head: "I'm not very good at doing this kind of data analysis. I've read a lot of statistics books recently, and it's really difficult."
Bai Ye thought for a while and said, "If it's convenient, you can send me the data and I will do statistical analysis for you?"
Xu Yan was stunned: "You have to take the postgraduate entrance examination? Where do you have time? Forget it, forget it, I'll just spend the money to find statistics from the Medical University. Junior brother, you should review it carefully."
Bai Ye didn't want to owe anyone a favor, and he couldn't afford the Book of Pride now, and it took a long time to buy it back. He said, "Sister, it won't take long. I have studied this statistics before, and I am good at mathematics."
.You send it to me, I will prepare it this afternoon and send it to you."
With that said, Bai Ye added Xu Yan's WeChat account.
After returning home at noon, Bai Ye directly turned on the computer, downloaded the spss software, and started working on it.
For Bai Ye, who has level 4 statistical skills, this analysis is too simple. It didn't take Bai Ye long to complete it.
However, Bai Ye felt it was a pity, because Xu Yan's experimental observation indicators and other aspects were very good and quite rigorous. Bai Ye felt that he could do better, so he re-created a file and prepared it for Xu Yan's thesis.
A mata analysis, with meta-analysis, Bai Ye felt that there should be no problems with Xu Yan's graduation thesis.
After finishing it, Bai Ye sent the materials to Xu Yan via WeChat.
He is more curious now, what exactly can he get in that lottery?
Thinking of the lottery, Bai Ye quickly went to the toilet and washed his hands with soap for a long time before clicking the lottery button.
What looked like a big turntable appeared in front of Bai Ye, and then started to spin. Bai Ye said silently to stop.
[Ding! Congratulations, you have obtained 10 memory capsules. Memory capsules can greatly improve your memory within five hours after taking them. 】
Memory capsule? Improve memory?
Thinking that Chinese medicine prescriptions require a lot of information to be memorized, Bai Ye suddenly felt confident that he might really be able to get into graduate school!
When Bai Ye originally signed up in October, he thought it was just for fun, so it seemed promising!
At this time, Xu Yan, after receiving Bai Ye's reply, opened the file and was dumbfounded.
The table lists more than twenty pages, analyzing each indicator in a clear and logical manner, and summarizing whether each difference has statistical significance.
Calculate the probability through spss software, and then get the conclusion that p<0.05, the difference is statistically significant.
Bai Ye is very serious, very detailed, and most importantly, professional, so professional that he cannot find any flaws.
At this time, he discovered that there was another file. After opening it, Xu Yan was dumbfounded.
mata analysis?
This junior can even do meta-analysis?
In order to publish a sci-fi article, Xu Yan studied mata analysis for a long time, but she still didn't know how to do it. Looking at the mata analysis designed by Bai Ye, Xu Yan was a little confused for a moment.
At this time, Xu Yan's roommate suddenly said: "Oh, I'm back. The data analysis I sent to the Medical University was sent to me. Xu Yan, come and take a look, what do you think?"
Xu Yan turned off her computer, walked over to the woman, and looked at the data analysis she opened. There were only four or five pages, and it was very simple. She analyzed the general indicators and briefly discussed them. In Xu Yan's words,
It's just mediocre and has no highlights.
Compared with what Bai Ye did for himself, it was far behind! Bai Ye gave detailed answers to the errors in each data, experimental analysis, and type one and type two errors.
Xu Yan asked: "Leilei? How much did you spend on this?"
The girl sighed: "I asked a friend to introduce me. It cost me less than 1,000. It's really expensive! But I want to get it out early and show it to my teacher. The end of the year is coming soon, and I will be busy looking for a job after the new year."
, where do you have time to write a paper? Just spend it and save your worries."
"Xu Yan, do you really plan to do it yourself? I think it's better to let someone do it professionally. When the time comes, there will be problems with the graduation defense, which will be even more troublesome. If you don't delay graduation, it will be over!"
Xu Yan smiled and opened her notebook: "Leilei, I've done it. Take a look, what do you think?"
As Xu Yan opened the first folder, the girl started reading while holding the notebook. A few minutes later...
"Holy crap! I actually have a creepy, unexplainable feeling! Xu Yan, did you ask your instructor to do this?" the girl shouted in a fuss.
Xu Yan shook his head. In the afternoon, Xu Yan put what Bai Ye sent into his thesis and sent it to his tutor to see if there were any big problems.
Xu Yan’s mentor is Zhang Hanlin, who is the director of the Brain Disease Research Office of the University Hospital of Traditional Chinese Medicine. He has a doctorate in the United States. He has published many sci-fi articles and is good at scientific research.
Xu Yan handed over the printed paper and said, "Teacher, my paper has been revised. Please take a look at it at your convenience."
Zhang Hanlin happened to be fine at this time, nodded and said: "Xiao Xu, I read your proposal. It is quite meaningful. The important thing about the graduation thesis is the processing and in-depth mining of data. This is more challenging."
"Although your indicators are not the latest, the experiment was indeed done under my guidance. I think we should put some effort into statistics and deal with it properly. This is the top priority of the graduation thesis."
After saying that, Zhang Hanlin opened the data analysis at the back of the paper. However, at this moment, Zhang Hanlin suddenly froze, and then he frowned and fell into thinking.
this……
He continued to turn back, and the more he looked, the more frightened he became!
This analysis?
So detailed?
A simple two control groups, a blank group, and five indicators were analyzed in such detail?
And every point is done very well, and the best data analysis method is chosen.
Every experimental possibility and error was analyzed.
this……
Are you really reading a graduate thesis? Isn’t it an international core SCI article?
Is this really a graduate student level of analysis?
Zhang Hanlin frowned.
Even he himself is still far away from this data analysis...
