The behavior of the subjects in the experimental group and the control group is expected to be different due to the manipulation of the independent variable, which is the main purpose of the experiment. Error and chance occurrence may affect the results, but they are expected to be randomized and evenly distributed between the two groups. The dependent variable is the outcome variable that is being measured to evaluate the effect of the independent variable on the behavior of the subjects, so it cannot be a reason for the difference between the two groups.
