Report ANOVA Results Clearly & Correctly

Reporting an ANOVA correctly means presenting the right statistics in the right format so readers can fully understand and evaluate your results. This guide walks you through the key values to report and how to format them according to APA 7th edition guidelines.

F
F-Statistic
df
Degrees of Freedom
η²
Effect Size
p
p-Value
APA Reporting Templates
One-Way ANOVA F(df_between, df_within) = [value], p = [value], η² = [value]
Two-Way ANOVA – Main Effect F(df₁, df₂) = [value], p = [value], η²p = [value]
Interaction Effect F(df₁, df₂) = [value], p = [value], η²p = [value]
Non-Significant Result F(df₁, df₂) = [value], p = [value] (ns)

ANOVA Summary Table Format

A properly formatted ANOVA summary table makes it easy for readers to scan your key statistics at a glance, alongside your written results.

Source SS df MS F p η²p Significant
Between Groups 245.30 2 122.65 8.94 .001 .18 Yes
Within Groups 1,108.50 81 13.68 - - - -
Total 1,353.80 83 - - - - -
Interaction 32.10 4 8.03 1.74 .149 .04 No
Note. SS = Sum of Squares; df = Degrees of Freedom; MS = Mean Square; η²p = Partial Eta Squared. Values are presented following APA 7th edition guidelines for ANOVA result tables.

How to Write ANOVA Report

Run the ANOVA in Your Software

Use SPSS, R, or a similar tool to run your one-way, two-way, or repeated-measures ANOVA and generate the output tables.

Identify Key Values from Output

Locate the F-statistic, degrees of freedom (between and within), and the p-value from your software's ANOVA table.

Calculate Effect Size

Determine eta squared (η²) or partial eta squared (η²p) to show the practical significance of your findings.

Write the APA In-Text Statement

Combine your F-value, degrees of freedom, p-value, and effect size into a single APA-formatted sentence.

Format the Summary Table

Present your results in a clean APA 7 style table with appropriate headings, notes, and decimal precision.

Do's & Don'ts When Reporting ANOVA

Degrees of Freedom

Always report both between- and within-group degrees of freedom alongside your F-value.

✓ F(2, 81) ✗ F = 8.94
p-Value Format

Report the exact p-value to three decimal places rather than using a vague inequality.

✓ p = .032 ✗ p < .05
Effect Size

Always include an effect size measure so readers can judge the practical importance of your result.

✓ η²p = .18 ✗ Omit effect
Table Formatting

Reformat raw software output into a clean APA-style table rather than pasting it directly.

✓ APA 7 table ✗ SPSS raw
