Experimental variables need to be controlled because they can cause the experiment to be flawed. Variables can change the experiment, and even if it's not a very big change, it will still make the experiment unreliable. For example, let's say a person is trying to see which laundry detergent is better. They stain four shirts with grass stains, and then apply detergent to each one. The experimental variable in that experiment is the stains; In order for the experiment to be accurate, the person doing the experiment must make sure that they put the same amount of grass stains on each shirt. Otherwise, it would be a very incorrect, inaccurate experiment.
