No, control variables are not the ones changed in an experiment; rather, they are the factors that are kept constant to ensure that any observed effects can be attributed to the independent variable. By controlling these variables, researchers can minimize their influence and isolate the relationship between the independent and dependent variables. This helps improve the reliability and validity of the experiment's results.
The number of control variables that can be included in an experiment is not fixed and can vary based on the design and complexity of the study. However, it's important to balance the number of control variables with the feasibility of the experiment, as too many can complicate analysis and interpretation. Researchers should aim to include only those control variables that are necessary to minimize confounding factors and enhance the validity of the results. Ultimately, the key is to maintain clarity and focus on the primary research question while controlling for relevant variables.
You need to control variables in an experiment so as to make sure that only the variable you are testing and changing is the one affecting the results of your experiment. For example, in an experiment to find the effect of light intensity on the rate of photosynthesis of plant, you'll change light by putting a plant in sun and another in dark but you must not change carbon dioxide level for both plants so by that you have controlled other variables in the experiment(variables which must be the same always in the experiment).
Those are the variables of the experiment.
To accurately identify the control group for the experiment, more context about the specific experiment is needed, including its objectives, methodology, and the variables being tested. Generally, a control group is a baseline group that does not receive the experimental treatment or intervention, allowing researchers to compare the outcomes with those of the experimental group that does receive the treatment. If you provide more details about the experiment, I can give a more precise answer.
In a scientific method (or experiment), a dependent variable is one that changes throughout the experiment. These are the ones whose changes need to be recorded. Independent variables are those that influence the experiment, but do not change throughout the experiment and remain the same value.
In a controlled experiment, the control variable is the one specific thing that is kept constant to measure the change of the other variables. Those variables are the parameters that are being tested.
Variables are simply names used to refer to some location in memory - a location that holds a value with which we are working. It may help to think of variables as a placeholder for a value. in system
To conduct a controlled experiment, you need to control all variables except the one you are changing. The variable you change is called the independent variable, and the variable you measure in response is the dependent variable. Control variables are those that could potentially affect the outcome of the experiment but are kept constant to isolate the effect of the independent variable.

An internal variable will change due to computations in the program module. An externalvariable will change due to other changes (external input).
If you're performing an experiment in which your result depends on multiple variables, but you're just interested in how one of those variables effects the result, you would generally keep all of the other variables constant in order to negate their effects. Those variables that you're keeping constant are called control variables, and you would choose them based on the experiment. For example, say you wanted to determine how changes in resistance effect a circuit's current. Well, current is dependent on not only resistance, but voltage as well, and since you're only interested in the effects of resistance, you would make voltage the control variable, keeping it constant.
Those are the variables of the experiment.
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.
In a scientific method (or experiment), a dependent variable is one that changes throughout the experiment. These are the ones whose changes need to be recorded. Independent variables are those that influence the experiment, but do not change throughout the experiment and remain the same value.
Independent variables are those that you change in an experiment. Dependent variables are the ones that you measure in an experiment. Dependent variables are influenced by the independent variables that you change, so they are dependent upon the independent variable. Generally, experiments should have only one independent variable.
