Since the Scientific Method is stated in varying ways, I would have to say it would be at whatever step in the version you have been taught, that the testing is designed.During which step of the scientific method would you identify variables and figure out how to control them?

Second step is your hypothesis


Third step is determining the method, which would involve identifying the variables and figuring out how to control them.
