APA style (American Psychological Association) provides a standard format for writing research results, including correlation results like Pearson’s r.

APA reporting ensures your findings are:

✅ Clear
✅ Professional
✅ Easily interpreted by readers

🔱 Basic APA Format for r

There was a [strength, direction] correlation between Variable 1 and Variable 2,
r(df) = r-value, p = p-value.

đŸ§Ș Example:

There was a strong positive correlation between study time and exam scores,
r(78) = .67, p < .001.

đŸ§± APA Template Breakdown

Component Example Meaning
r r(78) Correlation coefficient, with degrees of freedom (N – 2)
= .67 r = .67 Effect size (strength & direction)
p < .001 p = .003, p < .05 Probability the result is due to chance

📌 Degrees of freedom (df) for Pearson's r:

df = N – 2
→ If N = 80, then df = 78.

💡 Reporting Interpretation Tips

When writing, include:

✅ The direction: positive or negative
✅ The strength: weak, moderate, strong (use Cohen’s guide)
✅ The significance: Is p < .05?
✅ The context: What do the variables mean?

đŸ§Ș Example 1 (Significant result):

There was a moderate negative correlation between stress and sleep quality,
r(98) = –.42, p = .002.

đŸ§Ș Example 2 (Non-significant result):

The correlation between hours watching TV and GPA was not significant,
r(55) = –.08, p = .54.

Correlation APA Statement Example
Strong, Positive r(78) = .82, p < .001 → “Strong positive correlation”
Weak, Negative r(45) = –.18, p = .23 → “Weak negative, not significant”
Moderate, Positive, Significant r(66) = .39, p = .01 → “Moderate positive, significant”

✅ Checklist Before You Submit:

  • Have you reported r, df, and p?

  • Did you describe the relationship (positive/negative)?

  • Did you interpret the strength based on Cohen’s guidelines?

  • Did you explain what the results mean in plain English?
