## What is Statistical Inference?

Statistical Inference is an independent study app built for students, self-learners, analysts, and anyone reviewing core inference ideas through focused practice.

Work through 160 questions across Fundamentals, Practical Skills, Common Pitfalls, and Advanced Concepts. Each question includes an explanation so you can understand why an answer works, not just whether you got it right.

Features:
- FSRS spaced-repetition intervals to help reviews land at the right time
- Weak-point heatmap to show where you need more practice
- Daily challenge for consistent study
- Mock exams for timed review
- Offline practice for commutes, classrooms, and low-signal moments
- No login required

Use it to review estimation, confidence intervals, hypothesis testing, p-values, sampling distributions, power, errors, likelihood ideas, and common interpretation traps.

Practice offline, no login required.
