Bai Ling looked at Qinglian in front of him silently, this was actually a girl with the intention of suing the emperor.

What she said, in addition to the diametrically opposite cause and effect of the matter, is basically the same as several major events in the dossier at present.

Bai Ling looked at the tea soup in his hand, "What's the use of approaching me?" I am a little medicine, can I still help you overturn the case? ”

"I can't use medicine, and I didn't think about asking for medicine to help me settle my grievances...... But Si Yao not only knows how to make the concubine happy, but also has won several commendations from the saint, I think that as long as I follow Si Yao, I can always learn more things......" Qinglian cried and said, "I and Xiaolan are soft-spoken, we are afraid that if the Chengqian Palace has to change people again after a while, then we will finally have no chance to take the turn......

"I've been rewarded several times by the Holy Lord, who told you, Rouge?"

“…… Be. Qinglian had no choice but to nod, "But this is none of Sister Rouge's business, Xiaolan and I are cousins, and I haven't talked to anyone else since I played the drum room." ”

Bai Ling gently turned the cup in his hand and said nothing.

Qinglian's initiative approach was indeed purposeful.

Although it is said that jumping up from the drum room, there is indeed a possibility of completely getting rid of the original identity of the crime, and the drum room is no longer a place where the sect department directly resides the criminals, but there are often palace people who are degraded here. And not every time there is a transfer, someone will check the specific content of the file of the transferred person in detail, but just find the corresponding file underground and replace it, so the whitewashing of this layer of identity is very effective.

If there is no identification or exposure from the people who knew each other before, Qinglian and Chulan are likely to become ordinary palace maids by this point, unless they are fortunate by the emperor one day, as long as they don't mention it, their past will be easily hidden.

But the two girls with no background stepped into the concubine's bedroom from the drum room in four years...... Can they really do it on their own?

If you take into account the proximity of time, it is very likely that Qinglian and Chu Lan had contacted Lin Jieyu in the Teaching Workshop Division before, and then they were slowly brought up

On the other hand, the other person Rouge, her file is mediocre, she is indeed the daughter of Linxia Yicheng, formerly known as Yan Zhi, but this name is too elegant, it doesn't sound like a maid but like a master, so it was changed to rouge.

However, Bai Ling couldn't tell what was wrong, and she always felt as if she was missing something.

There is a serious divide between intuition and evidence.

“…… I remember last time Chu Lan said that you are from He County, Huizhou Prefecture," Bai Ling put down the teacup, and his voice gradually softened, "Why do you have your own fruit forest in the mountains of Donglin Temple?" ”

……

Qinglian stayed in the east side hall for two hours, and even Bai Ling came out to take lunch in, Chu Lan lay on the small table in the courtyard, looking at the gate of the east side hall boredly.

Shortly after the afternoon, Qinglian finally came out of the room.

Bai Ling kept her in the house until she was no longer choking, and the redness of her nose and eyes had all receded, and there was no trace of crying at all, before opening the door and letting her go back to the middle of Rouge and Chu Lan.

Before leaving, Bai Ling explained two things to Qinglian.

One is that she intends to cling to and deliberately conceals her identity, Bai Ling can not pursue it for the time being, but correspondingly, as long as she and Chu Lan are still in Chengqian Palace for a day, they must not have any thoughts of going to the Holy Lord to redress their grievances.

The second is today's conversation in the house, she can't reveal half a point to anyone, even Chu Lan and Rouge, who she trusts the most.

In addition to kowtowing repeatedly, Qinglian really didn't know how to be grateful for a while.

Outside the house, Chu Lan ran to Qinglian's side, "Why have you been there for so long!" ”

"Oh, Bai Siyao told me about the matter over there in the Tai Hospital," Qinglian pursed her lips and reluctantly made a smiling expression, "By the way, this is the manuscript left over from the day before yesterday, let's get back to work." ”

Outside, Qinglian's voice was far away, and Bai Ling sat quietly at the table alone, gently holding his forehead.

Is it the right thing to do to raise your hand and let go of the Qinglian sisters?

If they were really Lin Jieyu's people, then they would probably have been shocked by the fact that they found out the details of the two sisters' teaching workshops.

Whether what Qinglian said today is true or false, there are many ways to verify it. But if this matter is reported directly to Granny Shu, these two sisters may not survive tonight.

There are a hundred and eleven ways to make an unqualified maid disappear inexplicably, perhaps a few months later a rotting corpse will be found in a dry well, or a well-known dry bone will be found on the shore of a lake, in a deserted courtyard, or even in a garden renovated a few years later.

Zheng Shu and Bao Yuan must have known that she had returned to Chengqian Palace at this moment. It's just that as soon as she came back, she first grabbed Qinglian into the house and questioned her, so Granny Shu and the others haven't come over to inquire about the results of checking the books for the time being.

So, when they come to ask, do you want to answer truthfully?

Bai Ling's five fingers were inserted into his hair, and he suddenly felt a little embarrassed.

She sat down at the table, struggling a little to think about the return for a while, while reaching out and pulling out the four or five manuscripts that Chu Orchid had copied vigorously.

This chapter is the first lesson that Bai Ling intends to teach in the Tai Hospital, about the formation and testing of hypotheses.

This point was decided after discussing it with Bai Yi. Rather than imparting flexible counseling skills and some theories based on empirical research, it is more important for the apprentices to establish the most basic experimental design ideas and causal reasoning skills, so she mixed some psychological statistics and research methods at the beginning of the lecture as an enlightenment for the psychology class.

Her gaze fell on the conclusion at the end of the first measure

Assumptions about something can be divided into null hypotheses and alternative hypotheses

The null hypothesis always assumes that the parameters of a thing have not changed, while the alternative hypothesis assumes that the overall parameters of a thing have changed. For example, if there is a burglary in the countryside, then the null hypothesis and alternative hypothesis for the suspicious object Zhang San are Zhang San is a good guy and Zhang San is a bad person.

When the null hypothesis is true, but the experimenter rejects such a hypothesis, it is a type I error

When the null hypothesis is wrong, but the experimenter accepts it, it is a type II error

In experimental design in psychology, both mistakes should be avoided, but with different priorities. When an experimenter makes a Type II error, if they are confident in their hypothesis, they can re-validate the experiment, for example, until they find the reason why the data is significantly insignificant.

However, when the experimenter makes a type I error, the harm caused by the type I error will be immeasurable because the phenomenon that does not exist in the first place is reported, so the phenomenon will be derived from subsequent research and application.

……

Bai Ling slightly loosened his brow......
