The independent variable in this study is smoking nicotine, as this is the variable being manipulated by the researcher. The psychology test is the dependent variable, as it is what is being measured to determine the effect of smoking nicotine. The participants are not the independent variable, but rather the sample being studied. The location of the study does not impact the independent variable.
