Answer: Experiment.

Explanation:

Suppose that we have two related variables, A (independent) and B (dependent)

We could design an experiment where we can manipulate the value of A at will, and we also can observe how the variable B changes.

This is called an experiment, where the objective is to see how the variable B is related to the variable A, and then try to make a model that explains this relationship.
