Independent/manipulated variable is the factor, or factors, under the control of the experimenter. Extraneous variable the factor, or factors, being held constant. From box 5. 1 john stuart mill and the rules of inductive logic: Jsm laid out a set of methods of (cid:498)agreement(cid:499) and (cid:498)difference(cid:499) and of (cid:498)concomitant variation(cid:499). A control group accomplishes the method of difference: taken together (cid:523)(cid:498)the joint method(cid:499)(cid:524), the methods of agreement and difference provide the necessary and. Studies with both experimental and control groups meet the conditions of mill"s joint method. sufficient conditions (i. e. the immediate cause) for the production of y. As findings are replicated, confidence in them increases: establishing independent variables: The experimenter has complete control over it and is creating the situations that research participants will encounter in the study.
