By increasing the number of subjects in each condition, we can potentially increase the representativeness of the sample and reduce the impact of individual differences on the overall results. This is a better option than decreasing the number of levels of the independent variable, as this would limit the scope of the study and potentially reduce the validity of the results. Using a two independent groups design or an experimental group-control group design may not necessarily address the issue of individual differences in subject performance.
