Run rigorous personal experiments — A/B tests to full factorial designs — and get honest statistical results in minutes.
ExperimentA helps you design rigorous personal experiments using factorial design — a method used in science and engineering to understand what actually matters.
Choose 2 or 3 factors, define levels for each, and the app generates a randomized experiment plan. Enter your results as you go, and ExperimentA computes a full ANOVA analysis on your device — no data leaves your phone for analysis.
Results are categorized clearly:
- Strong evidence: the factor has a statistically significant effect
- Evidence: a real effect is plausible but uncertainty remains
- No evidence: not enough signal to distinguish from noise
ExperimentA is a learning and exploration tool. It does not provide medical, health, or professional advice.
Features:
- Full factorial design (2^2 and 2^3 with replication)
- Randomized run order to reduce bias
- On-device ANOVA computation
- Clear, uncertainty-aware result interpretation
- Built-in FAQ explaining key statistical concepts
