if you change more than one variable, you will not know which one has had an effect on the experiment. If the outcome changes when one variable is altered, then the change can only be due to the one variable, by logical deduction.
In a controlled experiment only 1 variable is being tested.
A variable is an element in an experiment that you control. There should only be one variable in an experiment or the results will not be accurate.
An experiment in which only one variable, the manipulated variable, is changed at a time is called a controlled experiment. This approach allows researchers to isolate the effects of the manipulated variable on the dependent variable, ensuring that any observed changes can be attributed directly to the variable being tested. By keeping all other variables constant, the reliability and validity of the results are enhanced.
Which variable is being tested in this experiment
The variable of the experiment that is being tested or the part that is changed by the person doing the experiment is called the independent variable... Thank you for letting me answer goodbye... ;)
One. If there is only one variable being tested, when you compare it to the control, you know that was the cause of a change.
In a controlled experiment only 1 variable is being tested.
A variable that doesn't change in an experiment is called a constant. Constants are used to ensure that only one variable is being tested for its effect on the outcome of the experiment.
A experiment should only have one variable.
It would not be a fair test if there were 2 or 3

A controlled experiment. In a controlled experiment, one variable (independent variable) is changed or manipulated while all other variables are kept constant to observe the effect on the dependent variable. This allows researchers to determine the specific impact of the variable being tested.

Which variable is being tested in this experiment
The only thing that should differ between experimental treatments is the variable being tested or manipulated. All other factors should be kept constant to ensure that any observed differences in outcomes can be attributed solely to the variable being studied.
controlled experiment where all variables are kept constant except for the one being tested.
