The dependent variable is the variable being measured or observed for change, and in this case, it is the sales of the brand of cereal. The independent variable is the variable being manipulated or changed, which is the shelf placement. The concomitant variation is a statistical term that refers to the natural variation of variables that are not being manipulated or studied. None of the options are adequate for the dependent variable, but sales of the cereal is the best choice.
