Is The Independent Variable Manipulated? The independent variable (IV) is the characteristic of a psychology experiment that is manipulated or changed by researchers, not by other variables in the experiment. For example, in an experiment looking at the effects of studying on test scores, studying would be the independent variable. Is the manipulated variable the
What Are Some Uncontrolled Variables? a characteristic factor that is not regulated or measured by the investigator during an experiment or study, so that it is not the same for all participants in the research. For example, if the investigator collects data on participants with varying levels of education, then education is an uncontrolled variable.
