📊 Executive Summary
✓ Statistical Validation Complete
Three independent tests confirm samples are from the same population:
- Persona Distribution: χ² = 1.39, p = 0.845 (No significant difference)
- Budget Distribution: χ² = 3.04, p = 0.694 (No significant difference)
- WTP Means: t = 1.42, p = 0.155, Cohen's d = -0.168 (Negligible effect)
Conclusion: Safe to combine datasets. Soft launch (n=84) and full launch (n=517) show no statistically significant differences in demographics, budget distribution, or WTP patterns.
Why Use Combined Dataset?
- Increased Statistical Power: 601 responses vs 517 (16% increase)
- Tighter Confidence Intervals: 95% CI narrows from ±$4.67 to ±$4.36
- More Robust Segmentation: Larger sample sizes per persona (avg 120 vs 103)
- Stronger Feature Correlations: Better detection of small-to-medium effects
- Adequate Power for Subgroups: Can analyze segments with n ≥ 30 reliably

Combined WTP Distribution
Willingness-to-pay distribution for all 601 responses. Shows clear premium market with median at $63, mean at $72.85. Right-skew indicates high-value segment opportunities.
Combined WTP by Persona
Box plots showing WTP distributions across all 5 personas with combined dataset (n=601). Enterprise leads at $91 mean, Marketing Pros at $82. Clear persona differentiation validates tiered pricing strategy.
Persona Distribution Comparison
Side-by-side comparison of soft launch vs full launch persona distributions. No significant difference (χ² = 1.39, p = 0.845) confirms sample compatibility.
Budget Distribution Comparison
Budget tier distributions across both launches. Consistent patterns (χ² = 3.04, p = 0.694) validate combining datasets. $26-$75 range dominates both samples.
WTP Box Plot Comparison
Statistical comparison of soft vs full launch WTP distributions. Overlapping quartiles and consistent medians ($63) confirm no significant difference (p = 0.155).
Technology Preference Shifts
Technology platform preferences across launches. AI/Vibe Coding and modern frameworks show consistent interest. Full launch provides better representation of diverse stack preferences.
🎯 Why Use Combined Dataset (n=601)?
✓ Statistical Validity
Three independent statistical tests confirm soft launch and full launch samples come from the same population. No significant differences in demographics, budgets, or WTP.
p-values: 0.845, 0.694, 0.155 (all > 0.05)
✓ Maximum Statistical Power
601 responses provide excellent power for detecting medium effects, analyzing 5-10 segments reliably, and conducting robust subgroup analysis.
Power: >80% for r ≥ 0.15 correlations
✓ Tightest Precision
95% confidence interval narrows from ±$11.98 (soft launch) to ±$4.36 (combined), providing most reliable pricing recommendations.
Improvement: 64% tighter confidence intervals
✓ Better Representation
Larger sample provides better coverage of underrepresented personas (Marketing, Personal, Agency), ensuring all segments have n ≥ 30 for valid analysis.
Min persona n: 32 (vs 3 in soft launch)
Recommendation: Use Combined Dataset for All Decisions
The combined dataset (n=601) provides the most reliable foundation for:
- Pricing Strategy: Tightest confidence intervals for price point recommendations
- Feature Prioritization: Strongest statistical power to detect feature-WTP correlations
- Persona Targeting: All segments adequately represented (n ≥ 30)
- Market Sizing: Most accurate demographic and budget distributions
- Product Roadmap: Most comprehensive understanding of customer needs
💰 Pricing Recommendations (Based on Combined Dataset)
Recommended 4-Tier Structure (n=601 Validated)
Based on combined dataset quartiles and persona WTP patterns:
25th percentile price point. Entry features for personal sites and budget-conscious SMBs. Market coverage: 20-25%.
Median WTP confirmed across both launches. Core features + analytics + AI tools. Expected adoption: 40-50%. Primary revenue driver.
