Simple main effects analyses involve comparing means for different levels of one factor within each level of the other factor. This is effectively a comparison of means considered two at a time. Etasquared analysis would not be relevant to simple main effects analyses, as it is a measure of effect size rather than a method of analysis. An analysis to reveal floor or ceiling effects would also not be directly relevant to simple main effects analyses, although these effects could potentially influence the interpretation of the results. The subtraction method is not a commonly used term in the context of simple main effects analyses, so it is not a relevant choice.
