Document Summary
Experiment where a researcher manipulates one or more variables, attempts to control extraneous factors, and then measures how the manipulated variables affect participants" responses. Regardless of the topic or wether the researcher"s goal is to test a theory, all experiments share a common underlying method: Try to keep other aspects of the situation constant. Experimental control includes the ability to: manipulate one or more ivs, choose the types of dvs; that will be measured, and how and when they will be measured, 3) so that the effects of the ivs can be assessed regulate other aspects of the research environment, including the manner in which participants are exposed to the various conditions in the experiment. The goal of having such control is to enable researchers to conclude that the variable that manipulate - rather than other uncontrolled factors _ is the cause of any obtained effects on behaviour.
