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 Account deletion with complete data removal
