Advanced Tutorial: Statistical Validation of a Synthesis

Tutorial: Statistical Prototype for Dialectical Synthesis Validation

This tutorial demonstrates the mathematical framework for validating CNS 2.0’s dialectical synthesis capabilities through statistically rigorous experimentation. The historical debate between Plate Tectonics and Geosyncline theory serves as our statistical prototype—a single, carefully constructed validation case that establishes the methodology for automated generation of n ≥ 30 synthesis pairs required for publication-quality scientific validation.

The tutorial implements the Experimental Validation Protocol from the Minimum Viable Experiment (MVE), providing the mathematical foundation and DSPy automation specifications necessary to scale from manual prototype to statistically significant validation across multiple scientific domains.

Mathematical Framework for Statistical Validation

Power Analysis and Sample Size Determination

For detecting synthesis quality improvements with statistical significance:

Target Effect Size: Cohen’s d = 0.8 (large effect)
Significance Level: α = 0.05 (two-tailed)
Statistical Power: 1-β = 0.80

Sample Size Calculation:

n = 2 × (z_α/2 + z_β)² / d²
n = 2 × (1.96 + 0.84)² / 0.8²
n = 2 × (2.80)² / 0.64
n ≥ 25 synthesis pairs (minimum)
n = 30 synthesis pairs (target with safety margin)

Primary Statistical Hypotheses

H₀: μ_improvement ≤ 0 (no systematic synthesis improvement)
H₁: μ_improvement > 0.1 (meaningful synthesis improvement over parent SNOs)

Success Criteria:

• Primary Endpoint: Mean synthesis trust score improvement ≥ 0.1 (p < 0.05)
• Secondary Endpoints: Ground truth alignment ≥ 0.85, synthesis coherence ≥ 0.9
• Effect Size: Cohen’s d ≥ 0.8 for practical significance
