Since 2014 I've tried to illustrate various statistical concepts using interactive visualizations. This page contains an updated overview of my visualizations.

Maximum Likelihood

An interactive post covering various aspects of maximum likelihood estimation.

Cohen's d

An interactive app to visualize and understand standardized effect sizes.

Statistical Power and Significance Testing

An interactive version of the traditional Type I and II error illustration.

Confidence Intervals

An interactive simulation of confidence intervals

Bayesian Inference

An interactive illustration of prior, likelihood, and posterior.


Interactive scatterplot that let's you visualize correlations of various magnitudes.

Equivalence and Non-Inferiority Testing

Explore how superiority, non-inferiority, and equivalence testing relates to a confidence interval

P-value distribution

Explore the expected distribution of p-values under varying alternative hypothesises.


Interactively compare the t- and normal distribution.


I used to sell posters on Etsy, but after making 95 sales (a magic number in science) I decided to stop and share the digital files here for free instead. You can print them in whatever way that fits you. If you want to support me just Buy Me a Coffee or share this page, or print the posters using this affiliate link Printful print-on-demand (it's the company I used when I sold these posters).
