How to Report ANOVA in APA 7

ANOVA reports should identify the effect, F(df1, df2), p value, effect size, and post-hoc comparisons when needed.

Updated:

Problem

ANOVA tables contain multiple effects. Without naming the effect and follow-up comparison, readers cannot know what differed.

Who should use this

Use this for papers, research reports, class statistics assignments, and SPSS ANOVA write-ups.

Formula and concept

Common APA fragment: F(df1, df2) = value, p = value, eta squared = value.

One-way ANOVA reports one factor. Two-way ANOVA usually reports two main effects and one interaction. If the interaction is significant, interpret it before relying on main effects.

Use eta squared or partial eta squared according to your course or journal. Label the effect size clearly.

This page helps with calculation and reporting, but users should still confirm their research design, assumptions, and statistical interpretation.

Step by step

  1. Confirm the ANOVA type and research design.
  2. Find the effect row and copy F, df1, df2, and p.
  3. Add an effect size such as eta squared or partial eta squared.
  4. If the omnibus F is significant with three or more groups, report post-hoc or planned comparisons.

Worked example

One-way example: Teaching method had a significant effect on posttest scores, F(2, 87) = 6.42, p = .003, η² = .13. Tukey comparisons showed the cooperative learning group scored higher than the lecture group. Two-way example: The interaction between method and grade was significant, F(2, 114) = 4.18, p = .018, partial η² = .07.

Common mistakes

  • Reporting only p without F and degrees of freedom.
  • Ignoring a significant interaction in two-way ANOVA.
  • Not explaining which groups differed after a significant omnibus test.
  • Mixing eta squared and partial eta squared without labels.

FAQ

Does a significant ANOVA mean every group differs?
No. It means at least one difference exists, so follow-up comparisons are often needed.
How do I write df1 and df2?
APA style usually writes F(df1, df2), such as F(2, 87) = 6.42.
How many results are in a two-way ANOVA?
Usually two main effects and one interaction, depending on the model and research question.
Can I report partial eta squared only?
Yes, if that is the required effect size. Label it clearly.

Next step

Generate an APA ANOVA sentence, then check the SPSS effect row and post-hoc output.
