Causation.
causation
The definition of a variable is to change or changeable. All variables hold this quality.
An independent variable stays the same even if other variables change.
true or false : in order to get the best results from an experiment, change as many variables as possible within the experiment?
You only change one variable; if you changed multiple variables you wouldn't know which one caused a change.

causation
The variable YOU change which will in turn effect another variable (the dependent variable). The controlled variable is plotted on the x - axis of a graph.
Independent variables are variables that can be changed in an experiment, while dependent variables are variables that change as a result of an experiment. In other words, independent variables are what you change, and dependent variables are the results of the experiment.

The experiment shows exactly what your title says!
the things you change
In an experiment, factors that you change are called independent variables.
