experiments test the scientist theory
If you test only one variable then you know that the difference in the experimental and control setup is that one independent variable. If you test more than one you will not know which one made the difference.
the test variable is the independent variable.
Doing so can enable you to pinpoint which independent variable had what effect on the dependent variable. If more that one variable is altered, there is no way of knowing which of them actually contributed to the change without doing further experimentation.
If you test more than one variable you don't know which one caused the changes.
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.

This variable is chosen by the research team according to the experiment project.
the test variable is the independent variable.
Dependent Variable is being tested or changed by the Independent Variable. (Wrong)The independent variable is typically the variable representing the value being manipulated or changed and the dependent variable is the observed result of the independent variable being manipulated. Experiments are usually designed to test the effect of the independent variable - so the dependent variable is NOT what it being tested.
