Benchmark Design & Analysis for Research Engineers
Design statistically valid benchmarks and interpret results
What You Can Do
You can design rigorous, reproducible benchmarks from first principles, establishing proper controls, baselines, and sample sizes. Claude analyzes performance results using appropriate statistical tests, calculates confidence intervals, and identifies whether observed differences are meaningful or noise. You'll produce peer-review-ready methodology sections and reports that satisfy the rigor demands of academic and production environments.
Features
establish proper controls, baselines, and experimental structure
choose appropriate tests (t-tests, ANOVA, Mann-Whitney U) based on data characteristics
calculate required sample sizes to detect meaningful differences
generate plots for trend analysis, distributions, and comparisons
quantify uncertainty and effect sizes with proper bounds
create detailed experiment logs and environment specifications
identify statistically significant deviations from baseline
structure multi-condition experiments with proper statistical framing
Example Output
Example 1: Benchmark Design Plan
## Benchmark Specification
- Primary metric: Throughput (ops/sec)
- Baseline: Current implementation
- Conditions: 3 optimizations vs baseline
- Sample size: 100 runs per condition (n=400 total)
- Warmup: 10 runs per condition
- Statistical test: One-way ANOVA + post-hoc Tukey HSD
- Confidence level: 95%
Example 2: Statistical Analysis Output
Results:
✓ Optimization A: +12.3% (95% CI: [10.1%, 14.5%], p<0.001)
✓ Optimization B: +8.7% (95% CI: [6.2%, 11.2%], p<0.001)
✗ Optimization C: +1.2% (95% CI: [-1.3%, 3.7%], p=0.34) — not significant
Effect sizes: Cohen's d = 1.42 (large), 0.98 (medium), 0.11 (negligible)
Example 3: Anomaly Report
Run 47 flagged: Throughput = 8,234 ops/sec (3.2σ below mean)
Likely cause: system noise (thermal throttling detected in logs)
Recommendation: Exclude from final analysis (outlier removal justified)
