Statistical Validation
Athletic Population
- Correlation with DEXA: r = 0.94
- SEE: ±1.5-2% body fat
- Test-retest reliability: r = 0.98
- Sample size: 500+ athletes
General Population
- Correlation with HW: r = 0.86
- SEE: ±3-4% body fat
- Test-retest reliability: r = 0.95
- Sample size: 300+ individuals
