Single-Subject RCT Dashboard
N-of-1 (Single-Subject Randomized Controlled Trial): Test whether intervention A (e.g., music) helps THIS specific child
Baseline (Week 1)
No music
Measure performance without intervention
Intervention (Week 2)
With music (120 bpm classical)
Introduce intervention
Baseline Return (Week 3)
No music (verify effect)
Remove intervention to confirm causality
Effect Size
+8.2 percentage points
Confidence
High (score dropped when music removed)
Conclusion
Music is effective for THIS child
Variability
Low baseline variability = clear effect
- 1. Baseline: Measure WITHOUT intervention (5-7 days)
- 2. Intervention: Introduce (5-7 days)
- 3. Baseline Return: Remove to verify (5-7 days)
- 4. Optional Reintroduction: Add again to triple-check
- 5. Calculate effect size = (Intervention avg) - (Baseline avg)
💡 Why this matters: Population studies (Aspirin helps 30% of people) don't tell you if Aspirin helps YOU. N-of-1 RCTs do.
