Changing only one variable in an experiment allows researchers to clearly determine the effect that variable has on the outcome. If multiple variables are changed, it becomes difficult to identify which variable is responsible for the observed results. This helps to ensure that the results are reliable and can be accurately interpreted.
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.
This variable is chosen by the research team according to the experiment project.
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.
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!!!
the investigator only changes one variable in an experiment because they need to see how that one variable reacts. if you wanted to see how the dependent variable changed but changed the independent variable you would not see how the one variable reacts.

Indpendent variable
a controlled experiment
the dependent variable is the only thing that changes in an experiment
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.
This variable is chosen by the research team according to the experiment project.

Independent variable : )
a controlled experiment
A experiment should only have one variable.
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.
