You can have more than one variable, but it would take longer to solve.
A controlled experiment
It depends on the experiment or the category. you welcome s.a No it's the variable k.a.
controlled variable is the factor that leaved unchanged to investigate any only one factor that has been changed in the other experiment and the effect of not altering this factor.
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... ;)
Which variable is being tested in this experiment
a controlled experiment
The term for an experiment in which only one variable is changed at a time is called a controlled experiment. This allows researchers to isolate the effect of that specific variable on the outcome of the experiment.

Independent variable : )
A controlled experiment is when only one variable, the manipulated variable, is changed at a time to observe its effect on the dependent variable, while keeping all other variables constant. This approach helps to determine the specific impact of the manipulated variable on the outcome of the experiment.
A single-variable experiment, also known as a one-factor experiment, is one in which only one variable is manipulated at a time while keeping all other variables constant. This allows researchers to isolate the effects of that specific variable on the outcome of the experiment.
A controlled experiment
It is an experiment in which only one variable is changed for example if I was seeing where a banana rotted fastest the only variable that would change is where the banana is placed.
Well in the case that it does have a variable, even just one, it would still be a variable experiment because that one part of the experiment may still cause a different effect/result when changed!!!
