InferForge
AP-Statistics inference for ages 15–18: a sampling-distribution simulator (CLT, histogram) + confidence-interval coverage, on a deterministic seeded sim with exact true moments — no AI near the stats.

#37474F Characters who teach
Meet the cast
InferForge's characters are realistic people, not mascots, and each one shows one idea in statistics: sampling, the bell curve, confidence intervals, p-values, biased samples, correlation versus cause, spread, errors, and randomizing. Professor Solano sets up each investigation and guides the reasoning.
Samira
Sampling distribution — one sample is a glimpse; many samples make a shape
Dev
The Central Limit Theorem — averages pile into a bell even when the data doesn't
Lena
Confidence interval — an honest range, not a false-precise single number
Tomas
Hypothesis test & p-value — how surprising is this if nothing's going on?
Corah
Sampling bias — who got left out changes the answer
Kiran
Correlation vs. causation — moving together isn't one causing the other
Sofia
Variability — the spread matters as much as the average
Malik
Significance & error — Type I vs Type II: which mistake are you risking?
Yara
Randomisation — random sampling and assignment are what let you generalise

Mentored by Professor Solano — no data leaves the device.
How InferForge handles your kid's data
- ✅ All progress, settings, and AI-generated content stays on the device
- ✅ No analytics, no tracking, no third-party SDKs
- ✅ Free — no ads, no in-app purchases
- ✅ No personal information collected from children — in line with COPPA (updated by the 2026 FTC amendments)
- ✅ No chat with strangers — play-together rooms use a short code and preset emotes, never typed messages
InferForge runs on ForgeKit — the open-source Swift Package Manager framework that powers every Spark & Anvil app. ForgeKit ensures consistent accessibility, COPPA compliance, and design language across the portfolio, so your kid's progress and preferences feel coherent across every app they touch.
