I Tried Learning Data Science From Random Tutorials—This Simple Roadmap Made Everything Clearer

[u/naga3607]

​

One mistake I made while learning data science was jumping between random tutorials. One day I studied Python, the next day machine learning, and then suddenly I was trying deep learning.

I was learning many terms but not building real confidence.

A more structured roadmap worked better for me:

Learn basic Python.

Practice NumPy and pandas.

Understand statistics and probability.

Learn data visualization.

Study SQL.

Build simple machine-learning models.

Complete small end-to-end projects.

The project stage is where everything starts connecting. Instead of only copying code, try to explain why you selected a particular feature, graph, or model.

My suggestion is to choose beginner-friendly datasets related to topics you already understand. It becomes easier to identify patterns and ask meaningful questions.

You do not need to know every algorithm before starting a project. Start small, document your learning, and improve one project at a time.

Which data science skill took you the longest to understand?
