Bayesian Correlation
v1.0.2
Sport Sciences context — reports the relationship between two continuous variables using BF₁₀. Is the haftalik_antrenman_saat ↔ VO2_max relationship real or due to chance? Supports Pearson/Spearman/Kendall.
🎯 What is it for?
Reports BF₁₀ instead of the classical correlation p-value; particularly valuable in small samples and replication studies. In the Sport Sciences context, the predicted direction of the relationship (ρ ≈ 0.68) between haftalik_antrenman_saat and VO2_max 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_antrenman_saat, VO2_max).
- Linear relationship (Pearson) or monotonic (Spearman/Kendall).
- Outlier checking should be done beforehand with Bland-Altman/scatter.

📄 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).
