When a main effect is found to be significant, it is important to further investigate the specific differences between levels of the independent variable. This is typically done through planned contrasts if specific hypotheses were made prior to data collection, or through post hoc contrasts if no specific predictions were made. Descriptive statistics provide an overview of the data, and the contrasts help in understanding where the significant differences lie, especially when there are more than two conditions within an independent variable.
