Seeing Theory
Seeing Theory uses visual explanations to introduce probability and statistics.
About Seeing Theory
Seeing Theory is an educational website that introduces probability and statistics through interactive visualizations. It is organized into six chapters: Basic Probability, Compound Probability, Probability Distributions, Frequentist Inference, Bayesian Inference, and Regression Analysis. Each chapter covers a set of core concepts, such as expectation and variance, conditional probability, the central limit theorem, bootstrapping, and ordinary least squares.
The site was created by Daniel Kunin while he was an undergraduate at Brown University. Its stated goal is to make statistics more accessible. The homepage marks the site as archived for reference, and the team describes a textbook based on the site as still in progress, with a draft PDF available for download.
