For biology class I need to create an experiment that tests different brands of dish soap on how effective they are at removing food residue. I know I could just put some sort of sauce on a plate and scrub it with the dish liquid and look to see how effective the soap is, but I want the experiment to be scientifically precise and I don't know how I'm supposed to make the data less opinionated and more factual.
