Architecture, Planning & Design context — tests the mean difference among 3+ groups with BF₁₀. It reports directly as evidence whether kentsel_doku (Tarihi, Modern, Kentsel Dönüşüm) groups have an effect on erisilebilirlik_skoru.

🎯 What is it for?

Instead of the classic F-test and p-value, it provides a separate BF₁₀ for each effect (main effect + interaction); a direct answer to the question “which effect really matters?”

📌 When is it used?

  • In Architecture, Planning & Design, comparison of 3+ treatments/categories — Tarihi vs Modern vs Kentsel Dönüşüm
  • When an interaction is present (2-way) — if the interaction BF₁₀ is larger than the main-effect BF₁₀, it changes the direction of the interpretation
  • Replication: reporting a “no effect” result with evidence

⚙ Assumptions

  1. Continuous DV (erisilebilirlik_skoru); categorical factor(s) (kentsel_doku).
  2. Independent observations; groups should be reasonably balanced.
  3. Homogeneity of variance — assumed for the pingouin BF computation.

📊 MerQur Output (summary)

Bayesian ANOVA (erisilebilirlik_skoru ~ kentsel_doku)
==================================
kentsel_doku main effect : BF₁₀ ≈ > 30 (very strong evidence for H₁)
Groups:
Tarihi μ̂ ≈ 55.00
Modern μ̂ ≈ 72.00
Kentsel Dönüşüm μ̂ ≈ 68.00

📄 APA 7 Interpretation

In the Architecture, Planning & Design field, the effect of the kentsel_doku groups (3 levels: Tarihi, Modern, Kentsel Dönüşüm) on erisilebilirlik_skoru was examined with a Bayesian ANOVA over 114 observations. The results yielded BF₁₀ > 30 for the main effect, indicating very strong evidence in favor of H₁. The highest mean was observed in the Modern group.

⚠ Common Mistakes

  • Use separate Bayesian t-tests for pairwise comparisons; do not over-interpret BF₁₀.
  • Unbalanced groups affect the BF estimate.
  • If an interaction is present, interpret the main effect together with the interaction.
