In a within-subjects design, each participant is exposed to all levels of the independent variables, which means fewer participants are needed compared to an independent-groups design. Therefore, the number of participants needed will change. The number of main effects and interactions that need to be examined remains the same, as does the number of cells (which is determined by the number of levels of each independent variable).
