C) when we have large samples
D) when we have a lot of power

When there is very little variability within groups, the differences between group means will be larger. This is because there is less overlap between the values of each group, making the distinction between them more pronounced. Conversely, when there is considerable variability within groups, the ranges of values for each group will overlap more, making it more difficult to discern differences between group means. The size of the sample and the power of the study are not necessarily related to the size of the differences between group means.
