Non Manipulated Independent Variable. The study by Schnall and colleagues is a good example. It is the presumed cause. The nonmanipulated variable is always held constant as a base of comparison against the manipulated counterpart Cite this page. Non Manipulated Independent Variable.
One independent variable was disgust which the researchers manipulated by testing participants in a clean room or a messy room. Non-manipulated independent variables gender can be included in factorial designs however they limit the causal conclusions that can be made about the effects of the non-manipulated variable on the dependent variable. The researcher measures it but does not manipulate it. The use of nonmanipulated variables is required when an independent variable exists without the experimenters intervention. In experimental research the aim is to manipulate an independent variables and then examine the effect that this change has on a dependent variablesSince it is possible to manipulate the independent variables experimental research has the advantage of enabling a researcher to identify a cause and effect between variables. The study by Schnall and colleagues is a good example.

Cis best done within an experimental design. Dcan answer questions about causal relationships between variables. It refers to the condition of an experiment that is systematically manipulated by the investigator. The use of nonmanipulated variables is required when an independent variable exists without the experimenters intervention. First nonmanipulated independent variables are usually participant variables private body consciousness hypochondriasis self-esteem and so on and as such they are by definition between-subjects factors. The non-manipulated independent variable was whether participants were high or low in hypochondriasis excessive concern with ordinary bodily symptoms.
