Stuck on a statistics problem? Take a photo of it and Stat Solver works it out step by step, then lets you ask an AI tutor about any step you don't follow. Calculators, statistical tables, formula sheets and 60 practice levels are in the same app. PHOTO SOLVER • Photograph a problem from your textbook, worksheet or screen, or pick a photo from your gallery • Add a question of your own if you want something specific explained • Get a step-by-step solution: the given data, the formula, every calculation and the final answer • Works on probability, distributions, hypothesis tests, confidence intervals, regression and more AI STATISTICS TUTOR • Ask anything about statistics in plain words: what a p-value means, when to use a t-test, how to read a regression • The tutor answers in your language, with proper notation (μ, σ, χ²) • Your conversations are saved in your chat history STATISTICS CALCULATOR • Descriptive statistics from your data: mean, median, mode, standard deviation, variance, range, count, min and max • Probability: factorials, permutations and combinations • Distributions: normal, binomial, Poisson, Z-score, t, chi-square and F, with graphs TABLES AND FORMULAS • Standard normal (Z), t, chi-square, F, binomial and Poisson tables • Formula sheets with examples for descriptive statistics, probability, distributions, inference and regression PRACTICE FOR YOUR EXAM • 60 quiz levels, from beginner to advanced, with an explanation for every answer • Choose the topics you need: descriptive statistics, probability, distributions, inference, hypothesis testing, regression, correlation, sampling, experimental design and non-parametric tests • Earn XP as you move along your learning path SHARE YOUR RESULTS • Share a solution with a classmate or a study group in one tap PERFECT FOR • High school, AP and college statistics students • University courses in business, psychology, nursing, biology, economics and engineering • Anyone revising for a statistics exam or checking their homework HOW IT WORKS 1.
