Response . This indicates that the population of the groups that we have analysed are not all equal, because all are different, or because only one of them is different. Having rejected the null hypothesis, further analysis is needed to determine which populations differ from the others. This can be done graphically (e.g. boxplots), by inspection of the media or through more formal tests, such as the Contrasts.
