Chapter 4 On the Importance of Handwashing in the Lottery

Bai Ye looked at the notebook and motioned, "Is it convenient for me to take a look?"

Xu Yan nodded, shrugging her shoulders to express her indifference.

Bai Ye took the notebook, opened the first page of the thesis, and read it roughly from beginning to end.

The title of the thesis is "Clinical Research of Tongqiao Huoxue Granules on Chronic Cerebral Ischemia". It is an observation of a clinical case. There are three experimental groups. The third group used the commonly used proprietary medicine Shuxuetong.

However, Xu Yan observed a lot of indicators, such as serum homocysteine, blood lipids, blood viscosity, cranial MRI examination, and transcranial Doppler ultrasound.

It is indeed a little difficult to make multiple comparisons before and after the experiment.

Bai Ye said: "Actually, senior sister, if the serum homocysteine ​​is compared, I think it can be divided into grades. According to what you mean, it can be divided into 4 grades to judge. You can use chi-square test or rank sum test To judge... If the blood lipids and blood viscosity are concerned, I think the t-test is also possible..."

Bai Ye talked a lot, and Xu Yan also seemed to be enlightened, but still shook his head: "I'm not very good at data analysis, and I've read a lot of statistics books recently, it's really too difficult."

Bai Ye thought for a while and said, "If it's convenient, you can send me the information, and I'll do statistical analysis for you?"

Xu Yan was stunned: "You have to take the postgraduate entrance examination? How can you have time? Forget it, forget it, I'll spend money to find someone who studies statistics from the medical university, and you should study hard, junior high school boy."

Bai Ye didn't want to owe favors to others, and he couldn't afford to buy the Book of Disdain, and even if he bought it back, it would be a long time ago, so he said, "Sister, it won't be long, I have studied this statistics before, and I am good at mathematics. .You send it to me, and I will send it to you in the afternoon after finishing it."

With that said, Bai Ye added Xu Yan's WeChat.

After returning home at noon, Bai Ye directly turned on the computer, downloaded the SPSS software, and started working.

For Bai Ye, who has statistical skills at level 4, this analysis is too simple, and it didn't take long for Bai Ye to complete it.

However, Bai Ye felt it was a bit of a pity, because Xu Yan's experimental observation indicators and other aspects were very good and rigorous. Bai Ye felt that he could do better, so he rebuilt a file and made it for Xu Yan's thesis. A meta-analysis, with meta-analysis, Bai Ye felt that there should be no problem with Xu Yan's graduation thesis.

After finishing, Bai Ye sent the materials to Xu Yan via WeChat.

He is more curious now, what can be drawn in that lottery?
Thinking of the lottery draw, Bai Ye hurried to the toilet, washed his hands with soap for a long time, and then clicked on the lottery draw.

I saw something like a big turntable appearing in front of Bai Ye, and then it started to spin, and Bai Ye stopped with a silent recitation.

【Ding!Congratulations, you have obtained memory capsule*10.Memory capsules can greatly improve memory within five hours after taking them. 】

Memory capsule?Improve memory?

Thinking of the need to memorize a lot of information on traditional Chinese medicine prescriptions, Bai Ye suddenly felt confident that he might really be able to get into the graduate school!
Originally, when he signed up in October, Bai Ye held the nature of playing tickets, and it seemed that there was really hope!

At this time, Xu Yan, after receiving Bai Ye's reply, opened the file and was dumbfounded.

The table lists more than 20 pages, and the analysis of each indicator is logical and well-founded, and the statistical significance of each difference is summarized.

The probability was calculated by spss software, and then the conclusion was p<0.05, the difference was statistically significant.

Bai Ye was very serious and did everything in detail, and most importantly, he was professional, so professional that he couldn't pick out 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 post an sci article, Xu Yan had studied mata analysis for a long time, but she was still clueless. Looking at the mata analysis designed by Bai Ye, Xu Yan was a little dazed for a while.

At this time, Xu Yan's roommate suddenly said: "Oh, I'm back, the data analysis I sent to the University of Medical Sciences was sent to me, Xu Yan, come and take a look, how about it?"

Xu Yan turned off her computer, walked to the woman, and looked at the data analysis she opened. It was only four or five pages long, and it was very simple. It's just mediocre, nothing special.

Compared with what Bai Ye did for himself, it was far worse!Bai Ye explained in detail the errors in each item of data, experimental analysis, and Type I and Type II errors.

Xu Yan asked: "Leilei? How much did you spend?"

The girl sighed: "I asked a friend to introduce it. It cost a little 1000, which is 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 work on papers? Just spend it, don’t worry.”

"Xu Yan, do you really plan to do it yourself? I said let someone else do it professionally. It will be even more troublesome if there is a problem in the graduation defense. If you can't make trouble and delay graduation, you will be finished!"

Xu Yan smiled and opened her notebook: "Leilei, mine is ready, take a look, how is it?"

As Xu Yan opened the first folder, the girl looked at it while holding the notebook. A few minutes later...

"Damn! I actually have a creepy, unaware feeling! Xu Yan, did you ask your mentor to do it?" The girl shouted in a fuss.

Xu Yan shook her head. In the afternoon, Xu Yan put the things sent by Bai Ye into her thesis and sent them to her tutor to see if there were any major problems.

Xu Yan's mentor is Zhang Hanlin, who is the director of the Brain Disease Research Office of the Affiliated Hospital of the University of Traditional Chinese Medicine. He has a doctorate in the United States. He has published many SCI articles and is good at scientific research.

Xu Yan handed over the printed thesis and said, "Teacher, my thesis has been revised, please take a look at it at your convenience."

Zhang Hanlin happened to be fine at the moment, so he nodded and said, "Xiao Xu, I have read your opening topic, and it is very meaningful. The most important thing for a graduation thesis is the processing and deep mining of data, which is more challenging."

"Although none of your indicators are up-to-date, the experiment was indeed conducted under my guidance. I think we should work on the statistics and handle them properly. This is the most important thing in the graduation thesis."

After finishing speaking, Zhang Hanlin opened the data analysis at the back of the thesis, but at this moment, Zhang Hanlin was suddenly stunned, and then he frowned, lost in thought.

This……

He continued to turn backwards, the more he watched, the more frightened he became!
this analysis?
so detailed?

A simple two control groups, a blank group, and five indicators have been analyzed in such detail?
And every point is done very well, and the best data analysis method is selected.

Each experiment possibility and error were analyzed.

This……

Are you really reading a graduate thesis?Not an international core sci?

Is this really a postgraduate level of analysis?
Zhang Hanlin frowned.

Even he himself is still far from this data analysis...
