An experiment involves three types of variable.
The independent variable is the one you are investigating. It is the one which you deliberately vary in the experiment. You should only have one independent variable.
The dependent variable is the variable which you measure to get your results. Often there is only a single dependent variable but there can be more.
All other variables must be controlled ie kept constant so they do not change the result. There are usually many control variables in an experiment.

How many variables should you change at a time in an experiment?

How many variables should be studied in an ideal scientific experiment?
ONE :)
How many variables does a controlled experiment have?
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.
How many variables should change in a scientific experiment?
It depends what kind of experiment you do. For some you just need one. For others you may change two variables. In most cases you only change one

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.

How many variables should be tested on the experimental group in an experiment?
Just one at a time
