CDI Resources: Free Edition

Open learning tracks you can start immediately

These resources are freely accessible learning tracks designed around real analytical workflow: how data is structured, what to check, what to trust, and how to interpret results.

Data Science

Start with Foundations, then expand into visualization, machine learning, and databases as you build depth.
