Planned comparisons are made when a researcher has a specific hypothesis regarding which groups should be included in the analysis. This approach allows for more targeted and focused comparisons, which can increase the statistical power and reduce the risk of making Type I errors. Unplanned comparisons, on the other hand, are exploratory in nature and do not have a specific hypothesis guiding them. Simple comparisons refer to the comparison of two groups, while post hoc comparisons are conducted after the main analysis to explore differences between groups not initially included in the analysis.
