BiasProof vs AP Statistics Practice

Master your biology. Battle your urges. Never get played. BiasProof is the cognitive bias training app that gamifies mental calibration. In realistic scenarios, you'll spot emotional traps, cognitive errors, and modern scams—building measurable resistance to the thinking pitfalls that derail decisions, relationships, and finances. Manifesto: Defend your mind. The world has changed. It's no longer just about "better decisions"—it's about defense. Your biology works against you: Biases like sunk cost keep you in bad jobs; anchoring fleeces you in deals. Your emotions tempt you: Urgency traps push impulse buys; trends override logic. Bad actors exploit you: AI-powered scams (pig-butchering, voice cloning) target human nature, not stupidity. We have antivirus for devices and locks for doors—but nothing for the software in your head. Until now. The Solution: Train like a martial art. BiasProof turns skepticism into a skill. No dry definitions—we simulate attacks: • Fake "urgent" investments • Tempting viral trends • Pressure-filled demands You make judgments, get instant feedback, and learn counter-moves. Progress through levels, earn streaks, badges, and climb leaderboards. Think of it as Strava for your brain. Why it works: Realistic scenarios from behavioral science Immediate feedback for muscle memory Gamification for daily habit (streaks, challenges, progress tracking) Measurable calibration: Track resistance over time Protect yourself from your own brain—and everyone else's scams.

AP Statistics Practice is a comprehensive learning app designed to help students prepare for AP Statistics through structured quizzes, topic-wise practice, mock tests, and performance tracking. Whether you are studying descriptive statistics, probability, sampling distributions, confidence intervals, hypothesis testing, regression, or experimental design, this app provides focused practice to strengthen statistical reasoning and problem-solving skills. Topics Included Exploring One-Variable Data Data distributions, measures of center, measures of spread, outliers, boxplots, and histograms. Exploring Two-Variable Data Scatterplots, correlation, linear relationships, regression lines, residual analysis, and association interpretation. Collecting Data Sampling methods, random sampling, surveys, experimental design, observational studies, and sources of bias. Probability Fundamentals Probability concepts, sample space, independent events, conditional probability, probability rules, and Venn diagrams. Random Variables Discrete variables, continuous variables, expected value, variance, and standard deviation. Probability Distributions Binomial distribution, geometric distribution, normal distribution, standard normal curve, z-scores, and applications. Sampling Distributions Sampling distributions, sample means, central limit theorem, standard error, sample proportions, and interpretation. Confidence Intervals Confidence levels, margin of error, estimating means, estimating proportions, critical values, and interpretation. Hypothesis Testing Null hypothesis, alternative hypothesis, test statistics, p-values, significance levels, and decision making. Inference for Means One-sample means, two-sample means, paired data, t-distributions, confidence procedures, and interpretation. Inference for Proportions Population proportions, one-proportion tests, two-proportion tests, confidence intervals, and sampling conditions. Chi-Square Procedures Goodness-of-fit tests, homogeneity tests, independence tests, contingency tables, expected counts, and chi-square statistics. Linear Regression Least squares regression, regression equations, slope interpretation, residuals, coefficient of determination, and model evaluation. Experimental Design Control groups, random assignment, blocking, replication, placebo effects, and experimental validity.
