ANOVA
Means across groups
ANOVA stands for analysis of variance, a statistical method for comparing means across multiple groups.
Rather than running separate tests between each pair of groups, ANOVA tests whether any of the group means differ significantly from the others: The ANOVA showed significant differences in test scores among the three teaching methods.
A foundational technique in experimental research.
