Want this question answered?
In a properly designed experiment, it is important to have at least 2 controlled variables. With two variables you are able to remove one at a time and see the effect in your setup.
It depends on the experiment or the category. you welcome s.a No it's the variable k.a.
The control is the variable that stays the same.The independent variable is the thing(s) that is being changed in the experiment.(don't have too many independent variables o your experiment will not work correctly).The dependant variable is the variable that depends the on the independent variable for the experiment.
An experiment of any kind can have infinitely many variables. A controlled experiment can have just as many, provided that all but one are kept exactly the same.
You can only change ONE at a time. That's what makes it controlled. It's the only sure way to know what actually changed the experiment.

They shouldn't, ever. It defies the whole point of a controlled experiment.

You only change one variable; if you changed multiple variables you wouldn't know which one caused a change.
1) I learned that you can have as many variables as you want. 2) You can change the variables. 3) Variables is used in an experiment. 4) A variable is something that can be changed, such as a characteristic or value. Variables are generally used in Psychology experiments to determine if changes to one thing result in changes to another.

All variables except one, the experimental variable, are kept constant in an experiment.
