The controlled variable is the variable that is kept constant , meaning not changed, throughout the entire experiment.
Constant means strait line and variable is an arch which is not a strait line
Variable is, logically, something that varies, that is to say, is not constant over time. Controlled variable, in the control field theory, is a variable measure that is, or that needs to be, controlled. Like a voltage that you need to keep under 10Volts because some devices in the setup have an amplitude limitation. Manipulated variable is usually a measure, a variable that you can measure. For example, if you can measure the voltage in the experimental setup then you can manipulate it, like using it to power a device. Constant variable, i think this is not very correct, a mathematician's opinion might be needed. For me is a variable, thus something that is variable over time, that under certain conditions becomes constant, thus stops varying according to time.
In a controlled experiment, the control variable remains constant while the experimental variable changes with each trial of the experiment.

The controlled variable is the variable that is kept constant , meaning not changed, throughout the entire experiment.
The factor that is kept constant in an experiment is called the controlled variable. It is important to keep this variable constant to accurately measure the effect of the independent variable on the dependent variable.
Controlled variable.
The difference between a controlled variable and a variable is in their state. A controlled variable is something which is rigid and constant while a variable is liable to change and inconsistent.
Controlled (in science) means constant and not changed. The opposite of variable.
Constant means strait line and variable is an arch which is not a strait line
what does controlling the variable mean?
In order for the results to be valid, the dependent variable can only be affected by the independent variable, so somethings need to be kept CONSTANT. The things that need to be kept constant are called CONTROLLED VARIABLES. Even if controlled variables are affecting the dependent variable(s), which they usually do, keeping them constant will ensure that all trials of an investigation were equally impacted by the controlled variables, therefore allowing one to see the impact of an independent variable on the dependent variable. All in all, a 'constant' in a science experiment should actually be called a 'controlled variable' and the description of such a variable is described in the third point. Hope this clarifies.
A variable that is kept constant in an experiment is called a controlled variable. This variable is deliberately kept the same throughout the experiment to ensure that any changes in the dependent variable are due to the changes in the independent variable.
A variable that is kept constant in an experiment is called a controlled variable. These variables are kept consistent or unchanged to ensure that any observed changes in the dependent variable are due to the manipulation of the independent variable.
A constant is a variable that remains the same and does not change its value during a specific process or calculation. This allows for consistency in mathematical or scientific equations.
