Examples of a fair test include control experiments where only one variable is changed at a time or repeat trials to ensure consistent results.
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.
experiments test the scientist theory
the test variable is the independent variable.
If you test more than one variable you don't know which one caused the changes.

Independent variable
The mediator variable explains the relationship between the independent variable and the dependent variable.
This variable is chosen by the research team according to the experiment project.

how do test a variable resistor
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.
