The independent variable is the only factor that is intentionally manipulated in an experiment in order to observe its effects on the dependent variable. In order to accurately determine the relationship between the independent and dependent variables, all other factors that could potentially affect the outcome (i.e. extraneous variables) must be controlled or held constant. Inferential statistics are used to analyze the results of the experiment, but they are not a part of the experimental situation itself. Placebos may be used in certain experimental designs, but they are not a necessary component of every experiment. Hypotheses are proposed at the beginning of an experiment, but they are not a factor that needs to be held constant during the experiment.
