19. Experimentation Independent Variable (IV): The Independent part is what you, the experimenter, changes or enacts in order to do your experiment. X axis Dependent Variable (DV): The dependent variable is what changes when the independent variable changes. There can be more than one dependent variable. Y Axis Control Group: Control Group: A trial in an experiment where all factors are kept from changing. Constants: unchanging qualities
