By trying to hold one or more variables constant.
For example, we know that car brakes will not work properly (car skids) due to a number of factors, type of car, whether the road is straight or curved, road conditions and car speed. We run experiments where the road conditions are exactly the same, and see at which speed the car begins to skid. Of course we should use the same car in all experiments. We should also drive the same section of road.

What are the classification of variables according to continuity of values in statistics?
what are the classification of variables
How do you describe variables in an experiment operationally?
Variables work by telling you what you need to change, what to observe, and what to keep the same in a experiment.
What is the difference between manipulated variables and controlled variables?
They are the same. These are names for the variables in an experiment that are controlled by the experimenter, as opposed to the output variables, the results you collect at the end of the experiment Hope this helped!
The variables in an experiment that stay the same?
These "variables" are called independent variables or constant variables meaning that they are capable of being changed by the experimenter but are intentionally held the same through each individual experiment.
The difference between the independent and dependent variables?
Independent variables are variables that can be changed in an experiment, while dependent variables are variables that change as a result of an experiment. In other words, independent variables are what you change, and dependent variables are the results of the experiment.
