After a significant single-factor ANOVA comparing four groups, what additional analysis is needed to determine exactly which groups differ?

Three groups have sample means that differ somewhat, but each group has very large variance. What effect does the large variance have on ANOVA’s ability to detect differences?

ANOVA evaluates differences among groups by considering both the differences between group means and the variation within the groups.
