control group & variable
The main thing that scientists plan and conduct is controlled experiments.
With controlled experiments it is taken into consideration what possible variables there could be and it is taken into account when conducting the experiment. This would mean that controlled experiments would produce more valid data.
they use controlled experiments to help them find out if it works or not.
To test the theory thoroughly, many controlled experiments were done.
There are many different kinds of controlled experiments. Most controlled experiments have many components that can be kept in check.

The independent variable is the variable that is varied or manipulated by the researcher. The independent variable is the presumed cause, whereas the dependent variable is the presumed effect.
