Calculus vs Introductory Statistics Tutor

Calculus you can see is calculus you can learn. Calculus: Learn & Practice turns a full first-year calculus course into one clear path: build intuition with an interactive animation, follow a worked example step by step, then prove to yourself you've got it with instantly graded practice. WHAT'S INSIDE • 51 interactive concept animations — play, scrub and watch the key change happen instead of imagining it • 119 worked examples with complete solutions, visual hints and the mistakes students usually make • 428 practice problems graded the moment you submit, each with a full solution • Math-history stories with the original problems: Zeno's paradoxes, Archimedes' π, Fermat and Descartes' fight over tangents • Mistake tracking and mastery per concept, so you know exactly what to review • Spaced review that brings a topic back right before you'd forget it • A searchable library of 9 chapters, filterable by topic, tag and difficulty TOPICS COVERED • Limits and continuity • Derivatives and differentials • Applications of derivatives — optimization, related rates, MVT, curve sketching, L'Hôpital's rule, Taylor polynomials • Integrals — FTC, substitution, integration by parts, partial fractions, improper integrals • Applications of integration — area, volume, arc length, work • Differential equations • Infinite series — convergence tests, power series, Taylor series • Multivariable differential calculus — partial derivatives, gradient, tangent planes, Lagrange multipliers • Multiple integrals — double and triple integrals Great for Calculus I and II, AP Calculus AB/BC review, and exam prep. Not covered, so you can decide before you buy: vector calculus (line and surface integrals). TRY IT FIRST Chapter 1 is completely free — animations, examples and practice all work, no time limit and no account. If you like it, one purchase unlocks every chapter forever. No subscription, no ads. Buy once, use on iPhone, iPad and Mac. Your progress stays on your device. Purchases are handled securely by Apple and can be restored anytime.

Introductory Statistics Tutor is a complete learning companion for an undergraduate introductory statistics course. Rather than relying on isolated quizzes or formula memorization, the app helps students build statistical understanding progressively through guided instruction, targeted practice, visual reasoning, interactive exploration, and mastery. Work through 15 major areas of introductory statistics, from data and study design through probability, sampling distributions, confidence intervals, hypothesis testing, regression, chi-square methods, and ANOVA. Each topic follows a Learn → Practice → Master approach. Guided lessons introduce the ideas and reasoning behind each method. Practice questions are explicitly aligned to lesson objectives, while Master assessments use less scaffolding and emphasize transfer, interpretation, study design, model diagnostics, and procedure selection. Statistics is visual. Questions are supported by purpose-built statistical graphics including distributions, boxplots, sampling models, confidence intervals, hypothesis-test regions, scatterplots, regression and residual plots, contingency tables, and ANOVA comparisons. Visuals are designed to represent the actual statistical structure and numerical information in the question. Interactive Explorers let you investigate concepts directly. Change parameters, make a prediction, observe what happens, and explain the statistical result. Explore sampling variability, the Central Limit Theorem, normal distributions, confidence intervals, p-values, proportions, chi-square methods, correlation, regression, ANOVA, and more. A built-in Interactive Statistics Reference provides help when you need it without simply revealing answers. Use it to choose an appropriate statistical method, review formulas and notation, check conditions and assumptions, improve statistical interpretation, explore distributions, and investigate important relationships such as sample size, standard error, confidence level, margin of error, and p-values. The app also includes cumulative review and exam preparation. Use Quick Review for a short mixed session, focus on weaker areas, practice individual topics, work through procedure-selection problems, or complete a 60-question Full Exam Simulation. Progress tracking emphasizes first-attempt understanding, helping distinguish material that has been mastered from concepts that need another look. Missed concepts feed into Review so students can return to the relevant ideas and practice them again. Introductory Statistics Tutor includes 88 guided lessons, 600 core questions, 120 dedicated Master questions, interactive statistical Explorers, adaptive study guidance, cumulative exam review, and a comprehensive interactive reference. Designed for students taking an introductory college statistics course, AP Statistics students seeking additional support, or anyone who wants to understand the reasoning behind statistical methods—not simply memorize which formula to use.
