Art of Stat Live

The Art of Stat app covers all your statistics and data science needs: from core concepts and probability distributions to data exploration, inference, modeling, and prediction. Free 7‑day trial, no credit card required. Use pre‑implemented datasets, import your own CSV/Excel files or, for smaller datasets, provide them directly. Created by an expert college professor with many years of experience teaching Statistics & Data Science. Better than AI: a guided, step‑by‑step learning experience—from summary statistics and visualization to understanding statistical methods and outputs, including stunning visualizations. (YouTube channel coming soon!) Learn Statistics & Data Science the right way. Unmatched visuals and interactivity. Not a photo HW solver. The app includes seven modules: - EXPLORE DATA Summary statistics, contingency tables, correlations, and rich visualizations: bar/pie charts, histograms, boxplots (including side‑by‑side), dotplots, and interactive scatterplots with color‑by‑variable. - DISTRIBUTIONS Interactively explore probabilities and percentiles for key distributions (Normal, Student‑t, Binomial, and more). Includes simulation tools. - CONCEPTS Central Limit Theorem (means/proportions), correlation and regression, confidence‑interval coverage, and Type I/II errors with power visualization. - INFERENCE Confidence intervals and hypothesis tests for proportions and means (one/two samples, independent/dependent), Chi‑square tests, and ANOVA. - REGRESSION Simple, multiple, and logistic regression; inference for parameters (SEs, CIs, p‑values); predictions; and striking interaction visualizations. - MACHINE LEARNING Supervised and unsupervised methods with train/test split, visualizations, predictions, heatmaps, and accuracy metrics including confusion matrices. - RESAMPLING Bootstrap CIs and permutation tests for means, medians, proportions, correlation, slope, and Chi‑square independence. Includes a Data Editor if you want to to create your own, smaller datasets. Works offline — perfect for exams or low‑connectivity environments.
