To understand this you need to remember that the independent variable is a condition that you can change, and the dependent variable is the outcome that you see.
If you have two independent variables, and you change both during an experiment, how are you going to tell which one caused the change to the outcome?
So, you only change one independent variable at a time.

∙ 9y agoYou need to control variables in an experiment so you can have greater confidence that what happens during the experiment is because of how you have manipulated the variable that interests you, the variable that you are studying. Without controls you are left with doubts about what actually brought about the results you observe... the variable you are studying, or some other variable that you did not account for.

When performing an experiment it is very important to have a control set. It is important to have a control set because it ensures that the experiment can be repeated as many times as necessary.

What are control variables important in experimenting?
the reason it is important to controll the variables in an experiment is because if the variables are not controlled in an experiment it will be impossible to reproduce the experiment. which also will make it impossible to prove the theory being tested
What are constant variables and y r they important in an experiment?
. Constant variables are variables which cannot be changed with the experiment. To remember their name is easy just think about Constance. They are important to an experiment because without all three variables there would be no complete experiment. Also the constant variables are important to an experiment because they help complete the result. Without a constant variable you. Would not be testing correctly
Why are the independent and dependent variables important in an experiment?
It is important because ............
Why is it important to control variables in a scientific experiment?
It is important to have controlled variables in a scientific experiment because it is the variable that remains the same it doesn't change. Its a consent & can be measured against.
It is important to control variables in an experiment because?
in an experiment cantrolling variable is important as it helps to identify the limiting factors are present in the experiment, and also factor that do not necessarily affect the experiment.

How many experimental variables should you have?
There's no "Limit", but the less you have, the better the experiment.

What are variables that do not change in an experiment?
Variables that do not change in an experiment are independent variables.
The variables that do not change in an experiment are what?
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.
Why is important to control variables in an experiment?
So that you can know what is the manipulating variable, the controlling variable, and the responding variable! To control the variables!
What are the variables in a scientific experiment?
There are 3 different variable. The independent variable is what you will be changing in the experiment and there should only be one. The dependent variable is what you will be measuring or observing. The controlled variable is what you will be keeping the same and there can be more than one. There is no limit on how many controlled variables you can have.
Why is it so important to control variables in an experiment?
You need to control variables in an experiment so as to make sure that only the variable you are testing and changing is the one affecting the results of your experiment. For example, in an experiment to find the effect of light intensity on the rate of photosynthesis of plant, you'll change light by putting a plant in sun and another in dark but you must not change carbon dioxide level for both plants so by that you have controlled other variables in the experiment(variables which must be the same always in the experiment).
