Using only two levels of a factor in a two-factor between-subjects design may not provide a complete picture of how the factor affects the dependent variable. This is because the effects of the factor may not be fully captured with only two levels, and there may be other levels of the factor that could produce different results. Therefore, using more levels of the factor can help provide a more complete and accurate understanding of how it affects the dependent variable.
