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.
To eliminate the possibility of hidden or unknown variables the scientist must run what kind of experiment?
To eliminate the possibility of hidden or unknown variables the scientist must a control experiment.
How can you eliminate confounding variables in your experiment?
To eliminate confounding variables, or variables that were not controlled and damaged the validity of the experiment by affecting the dependent and independent variable, the experimenter should plan ahead. They should run many checks before actually running an experiment.
What reason is the primary rationale for controlling variables in an experiment?
To eliminate alternative explanations for the result of an experiment
The variables that do not change in an experiment are what?
Variables that do not change in an experiment are independent variables.
What are variables that do not change in an experiment?
Variables that do not change in an experiment are independent variables.
What type of variables are in experiment?
the only variables in an experiment are the independent variables [the thing in an experiment your going to change. and the dependent variables [the thing in an experiment your going to measure.
When a variables is kept unchanged in an experiment it is said to be?
When a variable is kept unchanged in an experiment, it is referred to as a "controlled variable" or "constant." Controlled variables are essential for ensuring that any observed effects can be attributed to the independent variable, as they help eliminate potential confounding factors. By maintaining these variables, researchers can improve the reliability and validity of their experimental results.
What type of variables held constant in a experiment?
In an experiment, controlled variables are the factors that are held constant to ensure that any observed changes in the dependent variable can be attributed to the manipulation of the independent variable. By keeping these variables constant, researchers eliminate potential confounding effects that could skew the results. Examples of controlled variables might include temperature, time, or the type of materials used in the experiment. This allows for a clearer understanding of the relationship being studied.
What type of variables are factors that are being tested in a experiment and varied by the experiment?
Independant variables

What type of variables are factors that are being tested in and experiment and varied by the experiment?

What is the difference between a manipulative and a natural experiment?
in a manipulative experiment the investigator has control over the variables in the experiment. a natural experiment is simply making observations of naturally occurring events and looking for correlations between phenomena. Natural experiments are primarily just measuring and analyzing statistics.
