If your one-way ANOVA p-value is less than your significance level, you know that some of the group means are different, but not which pairs of groups. Use the grouping information table and tests for differences of means to determine whether the mean difference between specific pairs of groups are statistically significant and to estimate by how much they are different.
For more information on comparison methods, go to Using multiple comparisons to assess differences in group means[1].
Grouping Information tableUse the grouping information table to quickly determine whether the mean difference between any pair of groups is statistically significant.
Groups that do not share a letter are significantly different.
Tests for differences of meansUse the confidence intervals to determine likely ranges for the differences and to determine whether the differences are practically significant. Th...
