StatDrill turns intro statistics into a habit, not a chore. Instead of a fixed set of practice problems, every question in StatDrill is generated fresh from randomised numbers — so you can drill the same concept as many times as you need without ever memorising an answer key. WHAT YOU'LL PRACTICE • Descriptive statistics: mean, median, standard deviation, IQR, skew • Probability basics: addition and multiplication rules, conditional probability, Bayes' theorem • Probability distributions: binomial, normal, Poisson • Sampling distributions and the Central Limit Theorem • Confidence intervals (z and t) • Hypothesis testing: z-tests, t-tests, p-values, Type I/II errors • Two-sample tests: independent and paired • Chi-square tests: goodness of fit and independence • Simple linear regression • Correlation HOW IT WORKS Pick a drill mode — Adaptive (focuses on your weak spots), Topic Focus, Cram, or Quick Five — and StatDrill builds a session for you. Every wrong answer comes with a worked explanation, not just a correct/incorrect stamp, so you actually learn why. TRACK YOUR MASTERY StatDrill tracks your accuracy and streak per topic, so you always know exactly where you stand before an exam. FREE TO START Descriptive Statistics and Probability Basics are free, with 5 questions a day. StatDrill Premium unlocks all 10 topics, unlimited daily questions, and every drill mode. StatDrill is the practice companion to StatPilot — pull up StatPilot for a quick reference whenever a concept needs a refresher.
