I believe the what your referring to is the independent variable (changed). This is chosen and it is the relationship between the change in the independent variable which will cause a change in the dependent variable.
The factor tested in an experiment is typically called the independent variable. This is the variable that is deliberately manipulated or changed by the researcher to observe its effect on the dependent variable.
In an experimental study, the group that has one variable changed is typically called the experimental group. This group receives the treatment or intervention being studied, while the control group remains unchanged to compare the effects of the treatment.
In a controlled experiment, the group where the independent variable does not change is called the control group. This group serves as a baseline for comparison with the group where the independent variable is manipulated, helping researchers determine the effect of the independent variable.
The factor is called the independent variable. This is the variable that is deliberately changed by the experimenter in the experimental group to see its effect on the dependent variable.
Typically, in a randomised controlled trial (RCT), which is often used in testing the efficacy and use of drugs that about to be released into the market, there are two groups: The intervention group - receiving the treatment. The control group - receiving a placebo (hence the subjects believe that they're receiving treatment when they are not) Usually, patients are randomly allocated into the respective groups - otherwise this is known as a 'quasi-experimental' study.

a controlled group is like an idea but an experiment that is controlled cannot be changed.
control group and placebo group variable and controlled
In an experimental study, the group that has one variable changed is typically called the experimental group. This group receives the treatment or intervention being studied, while the control group remains unchanged to compare the effects of the treatment.
An investigation in science that is controlled is an experiment. The group within the experiment that is controlled is the control group.
In a controlled experiment, the group where the independent variable does not change is called the control group. This group serves as a baseline for comparison with the group where the independent variable is manipulated, helping researchers determine the effect of the independent variable.
The independent variable is the variable in an experiment that is deliberately changed or manipulated by the researcher.
the answer to that question is the control group has nothing to do with the independent variable because a control group is some thing in your experiment that has not changed through out your experiment. And a independent variable is some thing in your experiment that you change through your experiment(s)
A controlled experiment is a scientific study in which all variables are kept constant except for the one being manipulated or tested. This allows researchers to determine the direct impact of the manipulated variable on the outcome. By controlling all other factors, the experiment can establish a cause-and-effect relationship between the manipulated variable and the observed results.
An investigation in science that is controlled is an experiment. The group within the experiment that is controlled is the control group. A control experiment is designed to check or correct the results of a previous experiment. It does this by removing the variable or variables operating in the other experiment. The comparison obtained is an indication or measurement of the effect of the variables concerned
A variable test?
When a scientific experiment is carried out in a controlled setting, all variables are kept the same except for the control variable. The control variable is something that is constant and unchanged in an experiment, and is held constant to test the relative impact of independent variables.
