The Concept of the Control Group
A control group was a single group or multiple groups of experimental subjects that played an auxiliary and comparison role in scientific experiments that needed to be compared. It was a randomly selected sub-set of experimental subjects, with no special treatment for the individuals. In an experimental method with both an experimental group and a control group (control group experiment, also known as parallel group experiment), the control group and the experimental group were basically the same in terms of scope, characteristics, and so on. The significance of its existence was to highlight and strongly support the conclusions that could be drawn from the experimental group. Without a control group, it was difficult to determine whether the operation or some other variables (or several combined variables) had an effect. In literary creation (such as cross-book novels, cross-book sadistic novels, etc.), the concept of "control group" was borrowed to refer to a character or group of characters that formed a contrast with the protagonist (or main character). The differences in personality, fate, behavior, etc. were used to set off the protagonist or promote the development of the plot.

The difference between the control group and the control group
" Control " was an operational concept in an experimental method. It was a means of comparing the results of a certain experiment to clarify the influence and treatment effect or significance of a certain factor on a subject, except for the factors required to be studied or the treatment. The " control group " was a randomly selected sub-group in this kind of controlled experiment. It was the target group that did not receive experimental variables. Its role was to assist and compare the experimental group to highlight and strongly support the conclusions that could be drawn from the experimental group. The experimental group and the control group were basically the same in terms of scope, characteristics, and so on. The unrelated variables between the two were theoretically equal and balanced. In this way, the difference between the two could be identified as the effect of the experimental variables, thus making the experimental results credible.

The difference between the control group and the control group
As a Chinese word,"contrast" was to compare two different, opposite, and related things, or two different, opposite, and opposite aspects of the same thing. The purpose was to express the characteristics of things more clearly, which was also contrast. The "control group" was a concept in scientific experiments that required comparison. It played a supporting and contrasting role to highlight and strongly support the conclusions that could be drawn from the experimental group. It was a randomly selected sub-group of experimental subjects. The individuals in it did not receive special treatment. By setting up a control group, it could be determined whether the operation or some other variables (or several combined variables) had an effect.

The difference between the control group and the control group
The control group was the group that was compared with the experimental group in the experiment. It received the same experimental conditions as the experimental group, but did not receive independent variables. Its role was to compare the differences between the experimental group and the group that received the same experimental conditions but did not receive the treatment variables. The control group was a group used to control certain influencing factors in the experiment. The members of the control group did not accept the treatment variables, or accept the standard treatment that was generally known or accepted, or accept the known virtual treatment. Its role was to ensure the accuracy of the experimental results and eliminate the interference of other variables on the results. In summary, the control group was mainly used for comparison, while the control group was mainly used to control interference factors. In some experimental studies, they can be regarded as a comparison group of the same type of experimental group, but the meaning may be different in different research designs.

The difference between the control group and the blank control group
A control group was a single or multi-group experiment that played a supporting and contrasting role in scientific experiments that needed to be compared to highlight and strongly support the conclusions that could be drawn from the experimental group. It was a randomly selected sub-group of experimental subjects, and the individuals in it did not receive special treatment. Without a control group, there was no way to determine whether the operation or some other variable (or combination of variables) had an effect. A blank control group was a special type of control group. It referred to a control group that did not receive any treatment. It was commonly used in animal experiments and laboratory research methods. It could be used to assess the accuracy of measurement methods and to observe whether the experiment was in a normal state. For example, when studying the effects of a certain intervention on the experimental subjects, the blank control group would not receive any intervention, and other control groups might receive different treatments (such as model control, positive control, etc.) for comparison studies.

The differences and connections between the control group and the control group
As a Chinese word,"contrast" was to compare two different, opposite, and related things, or two different, opposite, and opposite aspects of the same thing to express the characteristics of things more clearly. The "control group" had a specific meaning in scientific experiments (such as biological experiments, random controlled trials in data science, etc.). It was a randomly selected sub-group of experimental subjects. The individuals in it did not receive special treatment. They played a supporting and contrasting role in the experiment to highlight and strongly support the conclusions that could be drawn from the experimental group. The connection between the two was that the "control group" was the concrete application of the concept of "control" in scientific experiments. By setting up a control group and comparing it with the experimental group, the comparison operation of "control" was realized, making the experimental results more credible and clearly showing the effects of the experimental variables.

Control group and what group?
The control group corresponded to the experimental group. In scientific experiments, the experimental group was a group of experimental subjects that received specific treatments or conditions, while the control group was a unit that was compared with the experimental group. The two groups were basically the same in terms of scope and characteristics. This kind of experiment with both an experimental group and a control group (control group) was also called a control group experiment or a parallel group experiment. In practice, a sample would usually be selected for research and randomly divided into a control group and an experimental group. Then, the results of the two groups would be compared.

The group pet's control group
In some stories, there was a comparison group for the team pet characters. For example, in one story, the junior sister was the favorite of the Fuyao Sect, while the senior sister was the opposite. The senior sister was unreasonable and devoted to the Dao. In contrast to the junior sister, the junior sister did not do proper work and was greedy for pleasure. The senior sister supervised her junior brothers and sisters in their cultivation every day and was quite diligent. In the story, Zhao Baozhu, the female protagonist of the group's favorite novel, was born lucky. Her family loved her, and her husband loved her too. She lived a rich and happy life. In contrast, Meng Yan was the group's favorite novel's control group. She was dark, thin, and short. Her parents did not like her, but her grandmother loved her. She was even described as a born bad child. She snatched Zhao Baozhu's things and her family's love. In the end, she married a country bumpkin. In the story of the Qingshui Brigade, there were two widowers who were like the control group. One was hardworking, determined, and loyal to love, while the other was sly, weak, and egoistic. They formed a contrast in different characteristics, just like the contrast between the group pet and the control group.
Forming a Control Group
In scientific experiments, to form a control group, one first had to determine the population of the experimental subjects, and then randomly select a sub-group from this population as the control group. The individuals in this control group did not receive special treatment. The purpose was to form a contrast with the experimental group, to help highlight and strongly support the conclusions that could be drawn from the experimental group. In practice, for example, to study the effect of a new drug on a specific disease, a group of patients with the disease would be selected as research samples. These patients would be randomly divided into an experimental group and a control group. The experimental group would receive the new drug treatment.(This was the special operation that the experimental group received.) The control group might receive a dummy or conventional treatment (that is, they did not receive the special treatment of the new drug). Then, the results of the treatment of the disease between the two groups were compared to determine whether the new drug had an effect. In some literary works, the concept of a control group would also appear. For example, the fate of different characters would be set as a control group, such as the different life trends of different educated youths, the different life situations of characters with different family backgrounds, etc. Through the description of these control groups, the plot development of the story, the character's personality, etc. However, this was not the formation of a scientific experiment control group in the strict sense. It was just a literary creation technique. The novel "Mother-in-law of the 60s and Daughter-in-law of the 80s" is equally exciting. Everyone is welcome to click and read it!
The meaning of the control group
In scientific experiments, the control group was a randomly selected sub-group of experimental subjects. The individuals in the control group did not receive any special treatment. It served as a support and comparison. In an experimental method with both an experimental group and a control group (control group experiment, also known as a parallel group experiment), the control group and the experimental group were basically the same in terms of scope, characteristics, and so on. The purpose was to highlight and strongly support the conclusions that could be drawn from the experimental group. Without a control group, it was impossible to determine whether the operation or some other variables (or several combined variables) had an effect. In literary creation (such as online novels such as cross-century novels), the concept of "control group" would also be used to construct the plot, forming a comparison through the different encounters of different characters.
