Visualizations
Since 2014 I've tried to illustrate various statistical concepts using interactive visualizations. This page contains an updated overview of my visualizations.
Statistical Power and Significance Testing
An interactive version of the traditional Type I and II error illustration.
Equivalence and Non-Inferiority Testing
Explore how superiority, non-inferiority, and equivalence testing relates to a confidence interval
Posters
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).

Thank you for making such useful and pretty tools. It not only helped me understand more about power, effect size, etc, but also made my quanti-method class more engaging and interesting. Thank you and wish you a great 2021!

We've mentioned your work a few times on our podcast and we recently sent a poster to a listener as prize so we wanted to buy you a few coffees. Thanks for the great work that you do!Dan Quintana and James Heathers - Co-hosts of Everything Hertz

For a high school teacher of psychology, I would be lost without your visualizations. The ability to interact and manipulate allows students to get it in a very sticky manner. Thank you!!!

Teaching stats to civil engineer undergrads (first time teaching for me, first time for most of them too) and grasping for some good explanations of hypothesis testing, power, and CI's. Love these interactive graphics!

Fantastic resource. I think you would be well served to have one page indexing all your visualizations, that would make it more accessible for sharing as a common resource.
