Learn statistics & data science, or teach it, with interactive visual apps built for the classroom. Free 7-day trial, no credit card required.
The Art of Stat app has the tools you need to learn (or teach) statistics & data science: from core concepts and probability distributions to data exploration, inference, modeling and prediction.
Select one of more than 50 pre-loaded datasets, import your own CSV or Excel files, or type in small datasets directly.
Created by an experienced college professor who has taught statistics & data science for many years.
A guided, step-by-step learning experience: from summary statistics and visualizations to understanding statistical methods and their output.
Try it free: 7-day trial, no credit card or subscription required.
The app includes eight modules:
EXPLORE DATA
Summary statistics, contingency tables, correlations and rich visualizations: bar and 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's t, Chi-square, Binomial and more), with simulation tools.
CONCEPTS
Central Limit Theorem (means and proportions), correlation and regression, confidence-interval coverage, and Type I/II errors with power visualizations.
INFERENCE
Confidence intervals and hypothesis tests for proportions and means (one and two samples, independent and dependent), Chi-square tests and ANOVA.
REGRESSION
Simple, multiple and logistic regression; inference for parameters (standard errors, confidence intervals, P-values); predictions; and interaction visualizations.
MACHINE LEARNING
Supervised and unsupervised methods with train/test split, visualizations, predictions, heatmaps and accuracy metrics, including confusion matrices.
RESAMPLING
Bootstrap confidence intervals and permutation tests for means, medians, proportions, correlation, slope and Chi-square independence.
DATA EDITOR
Import, edit and save datasets, or create your own in a spreadsheet.
Works offline, so it's ready for class, exams or places with poor connectivity.
