Bayesian Correlation
v1.0.2
Education Sciences context — reports the relationship between two continuous variables with BF₁₀. Is the haftalik_calisma_saati ↔ final_notu relationship real or by chance? Supports Pearson/Spearman/Kendall.
🎯 What is it for?
Instead of the classical correlation p-value, it reports BF₁₀; it is especially valuable in small samples and replication studies. In the Education Sciences context, the predicted direction of the relationship (ρ ≈ 0.52) between haftalik_calisma_saati and final_notu is tested with the Bayes Factor.
📌 When is it used?
- Two continuous variables — to seek direct evidence about direction and strength
- When you want to directly test the “no correlation” hypothesis
- As a replacement for a test that fails with p < .05 at small N
⚙ Assumptions
- Two continuous variables (haftalik_calisma_saati, final_notu).
- A linear relationship (Pearson) or a monotonic one (Spearman/Kendall).
- Outlier screening should be performed beforehand with a Bland-Altman/scatter plot.

📄 APA 7 Interpretation
⚠ Common Mistakes
- Pearson is misleading for non-linear relationships — check the scatter plot, and use Spearman if needed.
- Outliers inflate or mask the correlation.
- Correlation ≠ causation (especially in observational studies).
