The dependent variable is the outcome being measured or observed, in this case, the number of collisions. The independent variable is the type of cigarette (real or fake) and whether the participant smokes it or not. The use of a driving simulator and the driving skills of each driver are not dependent variables in this study. The use of nicotine is not specifically being measured as the independent variable in relation to the dependent variable.
