Learn With Numbers

The Library

The Library: other places we learn from

Data literacy is a movement. Here are some organizations and projects we would love to share and promote. Everything here is free unless marked otherwise. None of these are sponsorships or affiliates.

Organized the way we organize everything: understand, question, create.

Understand (learn the concepts)

  • Seeing Theory (Brown University). A visual, interactive introduction to probability and statistics. If a concept from our lessons isn’t clicking, seeing it move often helps. https://seeing-theory.brown.edu
  • StatQuest. Josh Starmer explains one statistical concept per video, clearly and slowly. A great second opinion on anything we teach. https://www.youtube.com/@statquest
  • 3Blue1Brown. The most beautiful math visualizations on the internet; start with the probability and Bayes videos. https://www.3blue1brown.com
  • Khan Academy, Statistics & Probability. Reference-style lessons and practice problems, free forever. https://www.khanacademy.org/math/statistics-probability
  • Gapminder. Hans Rosling’s project for testing your worldview against data. Take their quiz. Almost everyone scores worse than a chimpanzee, and finding out why is the lesson. https://www.gapminder.org

Question (spot the tricks)

  • Calling B.S. (University of Washington). An entire open course on spotting misleading data, taught by two professors. If our channel had a university-level sibling, this would be it. https://callingbullshit.org
  • Spurious Correlations. Tyler Vigen’s collection of absurd correlations, like cheese consumption versus bedsheet deaths. Correlation is not causation, made unforgettable. https://tylervigen.com/spurious-correlations
  • StatsChat (University of Auckland). Statisticians reacting to numbers in the news. https://www.statschat.org.nz
  • Full Fact. Professional fact-checkers at work. Fact-checking is a career our students should know exists. https://fullfact.org

Create (data and tools)

Looking for data of your own? Our Free Data Sources Online series shows where to find it and how to look around.
