"The time may not be very remote when it will be understood that … it is as necessary to be able to compute, to think in averages and maxima and minima, as it is now to be able to read and write."

— H. G. Wells, Mankind in the Making, 1903

What is

Colorful hand-drawn text reads "L WAN?" with a yellow L, red W, blue N, and black question mark.

Numbers are how the modern world argues. Learn With Numbers (LWN) is a series of courses that teach students to hold their own in that argument: to understand where numbers come from, question how they're made, and create honest analyses of their own.

Every project pairs academic rigor with real-world data: video games, sports, surveys, news... Along the way, the students build two skills that can outlast any tool: critical thinking and analytical storytelling.

The lessons are rigorous enough to be worth your time, and friendly enough to start at any level.

A collage with two children, a boy on the left and a girl on the right, both working on laptops. The boy has short black hair and is sitting at a desk with a globe, toy dinosaur, and toy fire truck behind him. The girl has long brown hair tied in pigtails and is smiling while using a silver laptop. The background for the girl is a bright room with shelves and plants. The collage has blue outlines around each child, and the word "LWN" is written in colorful letters at the bottom right corner.

There are two ways to learn with us. Every lesson we publish on our YouTube and social channels is free for everyone. You can follow the full curriculum at your own pace, without spending a cent, and that will never change.

For students who want a live teacher, classmates, and weekly feedback, we offer small-group live classes. Each course runs for 6 weeks and costs $50 per lesson. The price includes all course materials and an hour of weekly instruction in small groups. Students start with the first course and can progress through the program.

Space is limited, and enrollment is open for upcoming cohorts. You can signup today and pay after your first week!

Foundations

  • Turn messy numbers into clean tables, charts, and evidence-based claims.

  • Run experiments, crunch results with simple models, and share findings with posters and reports.

  • Turn your data into interactive dashboards and compelling visuals using free tools like Sheets, Looker, and Tableau.

Research

  • Use R and Python as your toolkit to clean, analyze, and visualize data while building hands-on projects.

  • Up your modeling game with GLMs, decision trees, clustering, and neural networks.

  • Dive deeper into the mathematics behind the models and understand their limitations.
