Whats a short example of an experimental variable?
Experimental Variable—the variable
that you are studying (changing)
in an experiment. It is the only variable
you change. hope that helps.
Example: If you want to know how speed affects
gas mileage, then speed is the only vari- able that should change. The
car, tires, road, wind speed need to stay the same—be controlled. They
are control variables.
