if you change more than one variable, you will not know which one has had an effect on the experiment. If the outcome changes when one variable is altered, then the change can only be due to the one variable, by logical deduction.

How many dependent variables do you want in an experiment?
In a controlled experiment only 1 variable is being tested.
What dose variable mean in science?
A variable is an element in an experiment that you control. There should only be one variable in an experiment or the results will not be accurate.
What variable is being altered in an experiment?
Which variable is being tested in this experiment
What variable is the part of the experiment that is affected by the independent variable that is being tested or the part that is changed by the person doing the experiment?
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... ;)
How many variables are generally tested in an experiment?
The trick to designing a good experiment is to figure out a way for it to test the effects of only one variable, and to avoid any effects of others.
How many variable should be tested and isolated in a good experiment?
One. If there is only one variable being tested, when you compare it to the control, you know that was the cause of a change.
How many dependent variables do you want in an experiment?
In a controlled experiment only 1 variable is being tested.
How many variables should have an experiment?
A experiment should only have one variable.
Why is only one variable tested at a time in an experiment?
It would not be a fair test if there were 2 or 3
What dose variable mean in science?
A variable is an element in an experiment that you control. There should only be one variable in an experiment or the results will not be accurate.
What is the importance of control set up in an experiment?
So you can make sure the results you gain are only due to the independent variable and not a variable not being tested.
What variable is being altered in an experiment?
Which variable is being tested in this experiment
How many variables can be tested at a time?
An experiment should test only one variable (the independent variable) at a time. If you are testing more than one variable at a time, you have no idea which variable is causing which effect.
What variable is the part of the experiment that is affected by the independent variable that is being tested or the part that is changed by the person doing the experiment?
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... ;)
When the chemist designs his experiment what should be the only independent variable?
temperature
What is a variable that is change in an experiment?
The dependent variable is the variable that can change in an experiment.
What is an experiment in which only one variable is manipulated variable at a time?
Controlled Experiment :Pcontrolled experiment.
