Roadmap to become a Data Scientist in 2023

Below you’ll find the Data Science roadmap - a step-by-step guide on how to become a Data Scientist. Mind that this track is heavy on statistics and that it's strongly recommended to discover the Data Science Foundation roadmap first!

The purpose of these roadmaps is to help you pick the right paths and to guide you if you are confused about what to learn next. Do you like to study on your own but with the support of a collaborative learning community? Then join the Data Science Roadmap - Study Circle.
